 Pidgin 2.5.1 has segfaulted and attempted to dump a core file.

 http://developer.pidgin.im/simpleticket/

 Please make sure to specify what you were doing at the time
 and post the backtrace from the core file.  If you do not know
 how to get the backtrace, please read the instructions at
 http://developer.pidgin.im/wiki/GetABacktrace

 If you need further assistance, please IM either SeanEgn or
 LSchiere (via AIM).  Contact information for Sean and Luke
 on other protocols is at

 Abort(coredump)
 : exdev.eu FSS 343 $;

 Looks like the server is sending a presence with a NULL nick which kill
 pidgin. Pidgin should not core in this case.
