List any ERROR messages you received:
the filter ends abnormally as soon as the user select a folder

Hi "gurus",
this is a thread appendix to the other one entitled indexprint.
Following the indications of moroquendo i downloaded/installed the extensions pack.
This solved indexprint problem: it runs on my PC!
Contactsheet on the contrary starts but ends abnormally as soon as the user select the input folder.
moroquendo did also a "clean" install on his windows 7 environment and got the same result (see his comment on the other thread).
It seems that the way the filter uses for accessing the folder is not appropriate for Windows (I have Windows 10, moroquendo Windows 7), while that same version works properly in Ubuntu.
Note that if the user does not perform the folder selection the filter starts (but does nothing obviously).
Only to learn a bit of python+windows+gimp:
- could a guru have a look into the code and see what's wrong?
Thanks a heap.



It's really to learn, because -having indexprint running- there is no strict need to have contactsheet also running (indexprint has replaced contactsheet, with improvements)

Edit:
PF_DIRNAME does not work in Windows+Gimp-2.8.20+python ?

Additional. Contactsheet does also not run in Gimp 2.8.20 for Linux.

More information. The first contactsheet was developed by Robert with Python 2.4 32 bits. Later I did the job first with 2.4 and then 2.6 32 bits python.

Well it works here, still talking Kubuntu 16.04 and Gimp 2.8.20



Only strange thing are the version numbers in the menu v. the plugin dialog 2.16 v 2.15 - an oversight.

Where it does not work is in Gimp dev version 2.9.5 where the error is
NameError: global name 'WHITE_FILL' is not defined
Beyond my limited powers to fix

Rich, a part that you are running Kubuntu, did you have a look into the code?
Is there something in the way the files inside the selected folder are accessed that perhaps requires some additional python feature?

Downloaded from node 120 (registry) contactsheet but it still refuses to work.

And... it is correct that you will see 2.15 and 2.16 that's an little bug you can easily correct.

But I'm now even more puzzled working on Kubuntu and not on Xubuntu

In earlier days you have to install Python for Gimp now it is more or less integrated in Gimp.

@Rich2005
Which version Gimp, Python, PyGTK, GTK2 do you use also 32 or 64 bits.

Kubuntu 16.04 64 bits with kubuntu-ppa backports enabled.
Gimp 2.8.20 from ubuntu ppa
python is 2.7.12 -this is a Gimp dependency = 2.7
py-gtk is the package python-gtk 2.24 - this is a Gimp dependency >=2.8.0
gtk2 - libgtk2.0-0 is 2.24.30 - this is a Gimp dependency >=2.24.1

Packing in for the night but I do have a Xubuntu VM that I use for assembling a Gimp 2.9.5 appimage. I will dig the base VM out of my archive tomorrow and see what happens.

for those able to read error log file, this is the error log when contactsheet crashes

Found the origin of the crash:
PF_DIRNAME does not work

Double-check: tried to run another python filter having that parameter (test_batch_cartoon.py), same crash



Is something missing in the environment Windows + Gimp 2.8.20 + Python 2.7?

I have the same so it must be something else.

Found an answer: https://stackoverflow.com/questions/408 ... pf-dirname

I will try the workaround.

(edit)
It works in windows

Many thanks!
Double-checked: it works!

I did a video capture of Xubuntu (VM) + Gimp 2.8.20 installation + contactsheet-v2.16.py but it is horribly boring, so just the result. Exactly the same source for Gimp 2.8.20 as my regular Kubuntu 16.04.

The plugin does throw up some errors but works with a default Gimp installation.

Indexprint is a different matter. I get plenty errors and a strange 'permission denied' even though permissions are set for all users. Installed all the required files pyexiv2, libglade2, python-gtk (comes in with Gimp) and the plugin fails with plenty of Gimp error messages unable to open file. Generates an image but it is blank.

Exactly the same setup in Kubuntu works fine. Trawled through all the installed python stuff on both, the same packages installed. First conclusion is the Xfce DE is the problem.

I modified contactsheet according the workaround: not working.
Starting Gimp -- verbose I saw too my surprise that contactsheet is not even parsed. Same for contactsheet-smallscreen.
Making contactsheet-smallscreen executable (I forgot to do that ) contactsheet-smallscreen pops up
Next what I did was contactsheet making not executable and executable again. Now it pops up. Very weird.

I have Xubuntu running with xcfe and Indexprint runs for me perfect. I will make a fresh installation with Xubuntu 16.04 onto a VM and try again what exactly is needed.

Have made a fresh Kubuntu (16.04.2) and Xubuntu (16.04) VM and no problems at all running Indexprint I have not tried contactsheet yet.
