I reproduced it, here is what I get in the console :

pure virtual method called
terminate called without an active exception
KCrash: crashing... crashRecursionCounter = 2
KCrash: Application Name = digikam path = <unknown> pid = 21184
sock_file=~/.kde4.1/socket-azmodan/kdeinit4__0

The backtrace is a little bit different :
