Comment 3 for bug 73414

some more information, I think there are actually two bugs.

Bug 1 - the notification area plugin is not working
Checkbox:
Enabling and disabling the checkbox by clicking on it (the checkbox) does switch the checkbox state but does not load the plugin nor gives any output.

Bug 2 - something in the plugin loading/unloading mechanism is wrong
Crash:
I can't reproduce the crash anymore, yesterday I could reproduce it every time by double clicking on the plugin (another way of (de)selecting the checkbox).
Also I would like to know how I can get the stacktrace for next time. I don't have any output in my terminal and I can't successfully start xchat-gnome through gdb (just did file and start).

Error message:
Double clicking wasn't really the problem. Just loading and unloading the plugin twice (load->ok->unload->ok->load->ok->unload->error) give me the error (this is also where it previously crashed). I discovered all the plugins give me this error but the others do (un)load though. Closing the settings window and starting it again let me (un)load all the plugins again, two times again.
-----------------------------
Plugin Unload Failed
An error occurred unloading /usr/lib/xchat-gnome/plugins/xxxxx.so
----------------------------

I do have my settings(xchat+gnome directory) migrated from a dapper box but I don't think this is the problem.
