Hi, Changed severity to "crash". I think I've seen similar crash elsewhere. What's new though is that I can reproduce. (was not the case before). Will see what I can do. After spending a couple of hours trying to figure out what's going on, without success, I gave a try to the same app, but linked agains Qt4.7 Miracle: no more crash. Since - the backtrace explicitly mentions issues inside Qt, at QPixmap deletion (which I though might have been triggered by some stuff in oxygen, but without finding anything wrong there) - the same crash can be seen (with Qt4.6) using the bespin style - the crash disappears when using Qt4.7 I (strongly) suspect a bug in Qt, that have been fixed for Qt4.7 (make sense ?) Closing as an upstream bug. |
