I was using kopete normally, it was idle on the system tray till I receive a new message from a friend. The notification went up but when it was going to dissappear kopete crashed with SIGABRT.

Relevant part of .xsession-errors:
-->
kopete: WARNING: KXMLGUIClient::setXMLFile: cannot find .rc file jabberchatui.rc
QFont::setPointSize: Point size <= 0 (-1)
QFont::setPointSize: Point size <= 0 (-1)
terminate called after throwing an instance of 'std::bad_alloc'
  what():  St9bad_alloc
KCrash: Application 'kopete' crashing...
kio (KIOConnection): ERROR: Header read failed, errno=104
kio (KIOConnection): ERROR: Header has invalid size (-1)
<--

And this is the backtrace:
