krash handler report for qt-4.6.0-3 when switching through windows
With -3 plasma-desktop isn't crashing right after enabling it. But if I switch through the open windows (only konsole and systemsettings) it is also crashing. The attached krash handler report is created after such a crash. But this time there is no selinux error.
When I reported this with -2 plasma-netbook crashed but I was able to switch trough the open windows to get the crash report. Now this is only hardly possible because the focus of the active window often gets lost and a half loaded plasma-netbook desktop is shown instead.
The behaviour is a bit similar to bug #550049.
That's a completely different issue, let's please track this separately.

Sure. I have only described this because libQtWebKit.so.4 was also mentioned in the crash.
I thought somewhere along the line that upstream had been notified of the selinux/jit problem, but I don't see that documented here or in any other previous bugs (bug #527079 or bug #516057)
Reported upstream, added reference to WebKit's bugzilla.
