random plugin loading problem

Hi,

I wrote a plugin few days back (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

Most probably those users either don't have GIMP with Python support or they did not set the executable bit on the plug-in.

I got it, at least in my case that is.

On ubuntu gimp-python is a separate package, unlike fedora. When I installed gimp-python, it works.
