Bug 203553 and bug 219297 are probaably the same. As you can always reproduce the crash, can you check the following: - Close all the Konqueror/Dolphin instances - Start Konqueror from Konsole as "MALLOC_CHECK= konqueror" (note the separation between the envvar (which we are setting to "" null) and the app name) If Konqueror doesn't crash now, then this is the glibc bug. (which should be fixed with glibc 2.11.1) Thanks 882806 2 aronasorman 2009-12-19 15:51:40 +0000 Seems you're right, konq doesn't crash anymore. So I should set this bug to RESOLVED, UPSTREAM? 882807 3 andresbajotierra 2009-12-19 15:52:42 +0000 I will mark it as duplicate of the glibc one.
