Application: plasma-desktop (0.4) KDE Platform Version: 4.7.3 (4.7.3) Qt Version: 4.7.4 Operating System: Linux 3.0.0-14-generic x86_64 Distribution: Ubuntu 11.10 -- Information about the crash: - What I was doing when the application crashed: I do have two "Application Launcher Menu"s on my default panel, a standard one and the other set to my "Favorites". When I click just on one it is OK, but as soon as I try to use the other BUM, the desktop crashes. So, the alternate use of the two different launcher menus on the default panel triggers the crash. - Unusual behavior I noticed: It happens every time The crash can be reproduced every time. -- Backtrace: Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault [Current thread is 1 (Thread 0x7f1de2e9d7c0 (LWP 11387))] Thread 4 (Thread 0x7f1dc2007700 (LWP 11390)): #0 0x00007f1dd781c034 in __pthread_mutex_lock (mutex=0x7f1dbc000a78) at pthread_mutex_lock.c:61 #1 0x00007f1dd6d0b649 in g_main_context_acquire () from /lib/x86_64-linux-gnu/libglib-2.0.so.0 #2 0x00007f1dd6d0cd81 in ??

Git commit b3758ba81a5d90a3c14d87d6fc54a653efbfa259 by Aaron Seigo. Committed on 12/12/2011 at 11:21. Pushed by aseigo into branch 'master'. disconnect even sub-menu MenuViews the previous fix only worked for the top-level view which had the models as parent. however, there can be other MenuViews which also share those models. the models are all stored in the header action list, so use that instead BUG:288687 M +7 -9 plasma/desktop/applets/kickoff/simpleapplet/menuview.cpp http://commits.kde.org/kde-workspace/b3758ba81a5d90a3c14d87d6fc54a653efbfa259
