This is the real bug: either the assertion is valid (in which case some bug is
causing it to be false), or it isn't (in which case it should be removed - this
is less likely, though).

The segfault for which you have reported a backtrace (Comment #2) is a symptom
of that, but I'd prefer to fix the real bug in empathy-chat rather than working
around the symptoms.

If you can reproduce this again with G_DEBUG=fatal-warnings in Empathy's
environment, that'll produce a different backtrace in which that warning is
treated as fatal, so the function at the top of the stack will be g_logv.
(fatal_warnings as mentioned in Comment #1 might also work, but fatal-warnings
is what the documentation says...)
