The crash might have been fixed with the commit above. Please test when packages for RC are available :-)
(In reply to comment #6) > The crash might have been fixed with the commit above. Please test when > packages for RC are available :-) Hello, after upgrading yesterday to 4.4.90, I had hoped that it was fixed, but unfortunately it is not. The exact same thing happens as previously noted. Not sure I mentioned before, I'm using Kubuntu 10.04.
the backtrace is the _exact_ same? (also do you really mean that both, windowmanager desktop -wallpaper, panels, plasmoids, etc- crash?) you /might/ be able to bypass this bug by "export QT_NO_GLIB=1" in ~/.xprofile or just "QT_NO_GLIB=1 kwin --replace &", but that's of course no fix.

Hello, here is the backtrace, also I was unable to find the .xprofile file so I created it but it didn't work, I was wondering do I need to log out and back in for it to have an effect?

a) the second backtrace does not match the first one at all. the second is about plasma-desktop (wallpaper, panels, etc.) while the first one is about kwin ("window titlebars") -> does kwin still crash? b) yes, you have to logout/login to apply .xprofile. alternatively you can set the environment when starting a process (what only makes sense if you can reproduce the same crash more or less reliably, though)
(In reply to comment #10) Hello, sorry about the non-matching backtraces. The kwin doesn't report that it crashes, now. Also I tried both of your suggestions and neither one seemed to work.
Thanks, so the kwin crash is actually fixed. For the plasma crash you should report a new bug report.

we still have reports for this in 4.7 - not being able to eat an event is somehow a major defect of the QGraphicsScene design... :-( I'll reopen this for the moment, sorry.
