I was connected to a gtalk account from meego-app-im, and repeatedly starting/ending calls between it and another gtalk account with empathy on a remote machine, to try to repro some other bug.
I'm not sure exactly at what point of this procedure gabble hit that assert. See attached logs and bt.
Note the warnings about CRC mismatch at the start of the bt. I installed debug info after the crash to have a better stack trace, so it may be off if packages were replaced in the repos.
Using version 0.12.2-16,4 as packaged on meego, so not so up to date code, but filing this anyway, as I never saw this before so probably hard to repro/check if fixed in new version.
