[JDEV] coredump in icq + 1.4.2-test (may be an old bug)

[Michael P. Cosby]

	I'm not familiar with the jabber codebase at all, so I don't know if
this bug is useful at all, but here goes - my jabber server coredumps
every couple of days and I finally convinced it to give me a core, so
here's the backtrace (peer.c is in the icq-transport).

The only jabber client used with this server is the CVS version of imcom
(http://imcom.floobin.cx)

The transports I have configured are yahoo, aim, icq, and msn (all the
latest from CVS, I'm pretty sure).

If you need the xml file I can send that along, too. I'll be saving the
coredump until the next time it crashes, so I can do more with gdb if you
need.
