evolution crashed with SIGSEGV in strcmp()

Binary package hint: evolution

evolution crashed while I was away from my laptop. The function names in the backtrace suggest that this crash was triggered by the reception of an email and evolution was trying to notify me. The following info may therefore be relevant for this bug:
 - I am running evolution from a KDE 4.2 desktop
 - some time before the crash plasma had crashed and restarted automatically (which may have disrupted the notification system)
