Python occasional "Unexpected error: [Errno 9] Bad file descriptor"

[opusGlass]

I have a batch python script that successfully runs through 22 images at a time, then crashes with the error "Unexpected error: [Errno 9] Bad file descriptor". After pointing it to the next set of images it continues for 22 more. Etc. ... Am I failing to properly dispose garbage or something?

Python plugin attached

Hello opusGlass.
I can't help you with this,
but there are a few really good coders here who can.

Since you appear to be on Windows, I would first remove/comment out all the "print" statements. When their accumulated output reaches 4K bad things happen (running the code gimp-console could alleviate this, too).

That was it! I noticed that it runs perfectly when pasted into the console but I didn't realize it was related to the print statements. Removing them fixes everything. Thanks!
