Reported using DrKonqi 884437 1 andresbajotierra 2009-12-22 00:49:11 +0000 I wonder if this could be related to bug 197936 or the glibc bug: bug 196207. Can you try the following: - Open Konsole - Run "killall krunner" (this will close Krunner) - Type "export MALLOC_CHECK_=" + Enter - Type "export QT_NO_GLIB=1" + Enter - Type "krunner" + Enter KRunner starts - Now use Krunner and try to repeat the crash - If you can still reproduce the crash at will, can you install the "kdelibs5-dbg" package and post a complete backtrace here? Thanks 884449 2 jonas743 2009-12-22 01:00:35 +0000 that seems to work. no crashes any more. 884452 3 andresbajotierra 2009-12-22 01:02:18 +0000 Nice to know, Merging with bug 197936. (distributions should provide the fix soon) Thanks *** This bug has been marked as a duplicate of bug 197936 ***
