*** This bug has been marked as a duplicate of bug 197717 *** You marked it Duplicated but this problem doesn't appear when I open/close windows.... For me it looks you say all of bugs with plasma are duplicated to bug of opening/closing windows.....? @Tom: The crash is caused by attempting to de-reference a NULL groupManager - exactly as in 197717. Whether it has the same user-visible cause is irrelevant - it's hitting the same flaw in the code, and the fix for 197717 should fix your bug, too :) See also http://aseigo.blogspot.com/2009/07/43-rc1-tasks-widget-crashiness-multi.html Also, check the backtraces, the lines and functions matches. Thanks *** This bug has been marked as a duplicate of bug 197717 *** |
