Bug 726915

> (evolution:4292): GLib-GObject-WARNING **: cannot register existing
> type `CompEditor'

Thanks for a bug report. Based on the above error I suppose there's some issue with linking, or something similar, because I cannot recall what was the issue when I saw it the last time, which is quite long time ago, with evolution-exchange and/or camel.

Is it easy to fix? I seriously hate having to access everything via webmail...

I'm not sure. I can invoke a rebuild of test packages for you, and we'll see. Are you using rawhide or F16 branch?

I see this when I run my local copy of evolution git master under valgrind, but nothing I can see in the code on the first look, except of the ';' being used in comp-editor.c in the G_DEFINE_TYPE_WITH_CODE, but changing it doesn't fix the issue:

There is a similar upstream bug too [1], there with spam assassin, but also with an extension. The extension framework seems to be broken for some reason. My memory is very poor, thus maybe it's not an issue with linking but with something else.

I'm sorry for a longer delay, but I got to this just recently. I built a test package [2] which has incorporated a proposed fix from the upstream bug report mentioned above. Could you give it a try, and report back, whether it helped you, please?

Seems to have nailed the problem. Evolution is working happily again :)

Thanks for the update. I'm committing the patch into upstream sources, and the fix will be widely available in 3.1.5 release.
