When i start konqueror from kickoff menu or the alt+f2 box, it crashes immedialely after its window opens. If it start from konsole, i got this: http://bugs.kde.org/show_bug.cgi?id=166865 It might be a bug in kdelibs (so please move this ticket as appropriate, i don't know where to place it correctly) because some other kde applications (including but akregator, kmail not including dolphin, konsole for example) behave simillary.
Konqueror traceback:

Application: Konqueror (konqueror), signal SIGABRT
