This crash is occurring regularly while using IRC with Empathy on Ubuntu 10.04. telepathy-idle is version 0.1.6-1, telepathy 0.10.1-1ubuntu2. Several users are experiencing it, see https://bugs.launchpad.net/ubuntu/+source/telepathy-idle/+bug/546246 I hope the trace is good enough, and the crash isn't already fixed! #0 0x007e1422 in

This backtrace doesn't make much sense: for instance, the frame above main() is tp_text_mixin_get_message_types(), which cannot be the case. And skimming the code, I can't see why a debug sender would be constructed in response to an incoming message — I don't see mismatched ref/unrefs or anything. I don't suppose you could reproduce the issue, and get an idle debug log (see <http://telepathy.freedesktop.org/wiki/Debugging>)?
I ran telepathy-idle in Valgrind with IDLE_PERSIST=1 IDLE_DEBUG=all. But I forgot to run valgrind with GSLICE=malloc, my bad! So the memory check is not interesting at all... I'll do it again, but for now here's the end of the log, if that can help: ** (telepathy-idle:5611): DEBUG: _parse_and_forward_one: message code 10 ** (telepathy-idle:5611): DEBUG: _parse_atom: parsing atom "andreasma!~andi@p4FE34B02.dip.t-dialin.net" as c ** (telepathy-idle:5611): DEBUG: idle_nickname_is_valid: Validating nickname 'andreasma' with strict mode 0 ** (telepathy-idle:5611): DEBUG: _parse_atom: set handle 252 ** (telepathy-idle:5611): DEBUG: _parse_atom: parsing atom "PRIVMSG" as I ** (telepathy-idle:5611): DEBUG: _parse_atom: ignored token ** (telepathy-idle:5611): DEBUG: _parse_atom: parsing atom "#libreoffice" as r ** (telepathy-idle:5611): DEBUG: _parse_atom: set handle 3 ** (telepathy-idle:5611): DEBUG: _parse_and_forward_one: set string "I get an issue with tabs inside the source code.
