"something like 10 times a day I suppose?!?" -> uncool @Martin: I /think/ "if( tab_grab ) tab_box->reset( true );" has to happen *before* "updateStackingOrder( true );" in Workspace::removeClient(), because the latter might/will/should cause an update on the tabbox (and the client is meanwhile gone) - yesno? *** This bug has been marked as a duplicate of bug 237345 *** |
Application: kwin (4.5.4 (KDE 4.5.4) "release 9") KDE Platform Version: 4.5.4 (KDE 4.5.4) "release 9" Qt Version: 4.6.3 Operating System: Linux 2.6.34.7-0.5-desktop i686 Distribution: "openSUSE 11.3 (i586)" -- Information about the crash: - Unusual behavior I noticed: kwin seems to regularly just crash on alt-tab between windows. There doesn't seem to be any logic there, it just crashes about every once every 30 times I switch windows... something like 10 times a day I suppose?!? The crash can be reproduced some of the time. -- Backtrace: Application: KWin (kwin), signal: Segmentation fault [KCrash Handler] #7 0x10478b10 in ??
