It should be documented. paynekj wrote: Regarding the pluginrc problem, did you check the permissions on the file before you deleted it? Yes, I explained previously that the file had the correct permissions. I did not delete it, I renamed it as you suggested. About the function arguments issue, here is a plug-in that works fine and has a similar argument problem. My plug-in uses a lot of the code from this example. #!/usr/bin/env python

I notice this has a gimp.context_push() and gimp.context_pop(). I tried applying them in the same place in my test plug-in and it crashed. What else is different? Why does this work and mine not?
