Hi,
I wrote a plugin few days back
(GimpPublishr<http://code.google.com/p/altcanvas/wiki/GimpPublishr>)
to publish images to Flickr/Picasa. It was tried by many and I had received
various complaints about plugin not getting loaded, even after deploying in
right directory. In some cases they had hit a bug in plugin which would
prevent Gimp from loading the plugin. In recent versions I fixed some bugs
in the plugin and put a top level try-except block with a crash report
dialog, so that any bug in plugin won't go unnoticed silently.
But even after that I kept hearing few cases where users won't see the
plugin loaded and still won't get any crash report.
Today I started working on the same plugin again after some gap. Today I
tried it under two different installations of Gimp - on my Fedora 8 desktop
and in a Ubuntu VM. I am running same version of Gimp at both places, using
same plugin files. Interestingly, the plugin doesn't load in my ubuntu VM,
but it does in my Fedora 8 desktop. I cleaned my $HOME/.gimp-2.4 directory
multiple times, but same result.
Note these observations:
1) I also noticed that when the plugin gets loaded successfully on my fedora
box, the $HOME/.gimp-2.4/pluginrc file gets modified and I see following
entry appended to it:
(plug-in-def "/home/jayesh/.gimp-2.4/plug-ins/publishr.py" 1202602069
I don't see that happening on Ubuntu VM.
2) On BOTH the systems, when the Gimp splash image is diplaying the plugins
it is loading at startup, I DO SEE publishr.py (my plugin file) being
loaded. But I doubt that the register() function gets called in the ubuntu
case. I put a deliberate "raise Exception" just before register() function,
however it doesn't make any difference.
Both are running same gimp version.
$ gimp --version
GNU Image Manipulation Program version 2.4.0-rc3
The dump of gimprc is same on both systems (except for the web-browser
parameter). For Fedora 8 it is as follows.

Can someone help me understand the plugin load mechanism? What variables
(built-in/environment/config) play role in plugin loading?
Thanks,
Jayesh
