Comment 1 Hugo Pereira Da Costa 2010-08-08 15:14:29 UTC 
Unfortunately its a Qt issue (or X11)
Deletion of pixmaps is not handled (directly) by oxygen, since everything is handled via QCache.
Comment 2 Unknown 2010-08-08 16:26:56 UTC 
So, should I report to the Trolls?
Comment 3 Hugo Pereira Da Costa 2010-08-08 18:01:24 UTC 
to comment #2: yes. Think so.
Though I think I've seen the same crash happens elsewhere already.
For my interest: how often does this crash occur ?
Comment 4 Unknown 2010-08-08 18:23:45 UTC 
Here it the report URL: http://bugreports.qt.nokia.com/browse/QTBUG-12743
Please, expand that, if you can.

This is the first time this bug encountered (and maybe this is why there were no duplicates here).
Comment 5 Unknown 2010-08-11 13:13:47 UTC 
Hmm, they closed the report; and unfortunately I cannot provide an application which presents how this crash works.
