The backtrace seems related to the one in bug 210146, but I can't be sure. In any case I think it is a Qt issue. Is your Qt build updated? Thanks I have found a possible testcase: You need - A taskbar with ~default~ settings (grouping ALWAYS enabled by name) (this may not be mandatory) - A sample application which sets itself to demand attention after some seconds (inspired by https://bugs.kde.org/show_bug.cgi?id=202199#c69) I have used a sample application created with KAppTemplate which uses a QTimer which after 5 seconds calls a slot calling "KWindowSystem::demandAttention(effectiveWinId(), true);" which will request the window manager attention and will made the taskbar to flash. - You have to run and minimize two instances of this sample application. The entries will appear and they will be grouped. - After X seconds the entries are going to flash (not noticeable as the grouped entry doesn't flash). - Now click the group entry to show the two of the real entries in the "list" - Select one of them The application window will be restored - Close that window. The whole group in the taskbar will dissapear (the spaces remains empty for a second) and Plasma crash with such a backtrace. Interestingly enough this doesn't happen with "plasmoidviewer tasks" Hope it helps. Regards happens for me too with qt46-nokia unstable I got same crash today, using Qt 4.6rc1 with KDE 4.4 from svn (built today).
I was closing Kmail's Composer window, when the crash occurred.

-- Information about the crash:
The title is a mouthful, but I always get a crash doing the following:
* Have 2 windows for an application open (Konqueror is the usual victim for me :( )
* Go to select one of the windows by clicking on the grouped entry, then the specific window (it doesn't seem to matter which one).
* Close the window you just selected.
* The taskbar will clear the grouped entry, appear to hang, and then crash Plasma. (backtrace should be attached).
BTW Dario, the crash reporting assistant is basically completely awesome. Just FYI
The crash can be reproduced everytime.

According to Alexis Menard, bug 210146 was fixed already (fix should appear on near future Qt build...), if this crash is the same, then this should be fixed too... @Michael: thanks ;) (if you get too much of those "errors" while reporting using the assistant, contact me so I will try to debug it...) Regards It's seems to be the same backtrace...So i would say it's fixed.... Updating bug info for posterity. Also, is this in kde-qt at all? I'm still getting the crash. :( *** This bug has been marked as a duplicate of bug 210146 *** It's not yet in kde-qt... |
