Looks like it might be an Oxygen issue. Could you try to run Dolphin in Valgrind:

valgrind dolphin 2> log.txt

(note that this will make Dolphin very slow), try to reproduce the crash, and attach 'log.txt' here then? This might provide some information about what went wrong before the crash. Thanks for your help!
Comment 2 Hugo Pereira Da Costa 2013-02-28 09:42:25 UTC 
also, would be nice to have debug symbols for oxygen style. 
valgrind log would be very useful also, yes

@Frank
 ... again, a crash in destruction chain
they're likely all related ...
Comment 3 Frank Reininghaus 2013-02-28 09:46:34 UTC 
Yes, they might be. I hope that a useful Valgrind log will help to finally nail down the cause of these crashes.
