Gajim crashes on startup with gir1.2-farstream-0.2 installed

This error does not provide much information, sadly.

It would be interesting if upgrading to

gir1.2-gst-plugins-base-1.0
gir1.2-gstreamer-1.0

these packages to version 1.14.1 fixes the problem

i cant reproduce the problem on debian 9

This is printed by
g_warning ("can't peek value table for type '%s' which is not currently referenced"
from glib/gobject/gtype.c

Maybe you would like to install additional debug packages like libglib2.0-0-dbgsym gstreamer1.0-plugins-base-dbg gstreamer1.0-plugins-good-dbg libgstreamer1.0-0-dbg libfarstream-0.2-5-dbgsym

and obtain the backtrace again with
$ G_DEBUG=fatal-warnings gdb --ex r --args python3 $(which gajim)

Same issue here. I get this from running "gajim -v" on bionic

Seeming telepathy-farstream causing this issue. https://dev.gajim.org/gajim/gajim/issues/9129

Removing gir1.2-farstream-0.2 fixes this issue for me. But empathy, pidgin uses it.

[Michael (michael976)]

Removing gir1.2-farstream-0.2 also "fixes" the crash for me.
