Reassigning
you have the debug symbols for Qt, but apparently not for kde related libs (notably kstyle, or oxygen). That would make it very hard to figure. Can you try add that your crash report? (don't ask me how though, I don't know. Someone more qualified should advise).
In fact this might be a duplicate of Bug 231841. Both crashes occurs in QX11PixmapData::~QX11PixmapData, (although this one occurs somewhat later in the destruction chain). I do not think this is oxygen related (in the sense that we never allocate pixmaps on the heap. (no "new" operator involved), so that the cleaning of these "shared" data is entirely in the hands of Qt.
