did you restart KDE after the update to 4.3.2? There were some crashes fixed in Coverswitch?
Yes, I restarted it (kdm session). It will maybee usefull that I use radeon driver.

Ok, so I probably missed one more case where it crashes. Are you able to reproduce the crash? If yes please give a very detailed description what has to be done to crash it. I have to be able to crash it myself in order to fix it ;-)

@Sebastián: thanks for reporting your backtrace. Unfortunately it is completely useless as you have not installed debug packages. And the backtrace has nothing to do with this bug report. This report is about a crash in kwin. Your backtrace looks like it could be Plasma. If you are able to reproduce the crash, please regenerate the crash and file a new bug report. Please use DrKonqui for that as it helps you to find the correct KDE component and does some checks on the usefulness of the report. Thanks.
Hi, I can't reproduce this bug. I'm still usign same versions (kwin, mesa drivers...), but I'm not seen this bug any more... So, it was probably a "random" bug.

*** Bug 225436 has been marked as a duplicate of this bug. ***
The code section where it crashes has been completely removed in 4.4 (it calls boxswitch code instead) as well the architecture of alt+tab has been changed significantly. This bug is most likely fixed in 4.4, but in case anybody is able to reproduce with 4.4 please reopen and attach a new backtrace or report a new bug.

Kevin please see https://bugs.kde.org/show_bug.cgi?id=437693 The rest of this bug is really old, so I'm closing this.
