gtg seems to require notify-python otherwise it crashes without fail upon closing the program, with the python error that pynotify can't be imported. Installing notify-python resolves the issue. I'm not sure why it isn't listed as a dependency by gtg (http://gtgnome.net/download/) but if notify-python allows gtg to create notifications, obviously we want that behavior anyway.
My mistake, I should have looked closer at the error: it is a requirement for the bugzilla plugin, but there are two problems with this: the error occurs even if the bugzilla plugin is disabled, and the bugzilla plugin can be enabled without the package being installed (other plugins ask you to install missing deps) Upstream bug report here: https://bugs.launchpad.net/gtg/+bug/1264846 I guess in the meantime notify-python can be added as a dep or we can patch the current package with the changes from revision 1388, where the bug was purportedly fixed (see https://bugs.launchpad.net/gtg/+bug/1264846/comments/1)
Still occurring with latest packages in F22
Well, I haven't pushed an update to gtg for a bit since upstream isn't making new releases at the moment. I'll add the required Requires to the spec and push an update. Cheers
