related bug, bt looks a bit different: https://bugs.kde.org/show_bug.cgi?id=189201
Steps to reproduce, works every time: 1. Open a new Konqueror window at http://grails.org/doc/1.1/ 2. Ctrl-F and type R, E, S, T (or some other matching four letter search string) 3. Press Esc to terminate the search. 4. Click any link in the page with the mouse. The browser crashes.
*** Bug 191521 has been marked as a duplicate of this bug. ***
Look at bug 191521 for a other detailed testcase(steps)
I never could reproduce those crashes, nevertheless I believe the many code-rugging measures I took in r961356 (that's been backported for KDE 4.2.3) should have taken care of that. Please report if that isn't the case!
Ok, I will try to update to the latest revision and update the bug status. Thanks
Testing on a recent SVN snapshot r984032 (qt 4.5.1), this bug appears to be fixed.
Ok, I can't reproduce the crash here using: Qt: 4.5.2 (KDE-Qt git commit 46a247a2c9a8c0c4456a02f6a0922d859d88fe76 Date: Fri Jun 26 13:45:37 2009 +0200) KDE: 4.3.60 (KDE 4.3.60 (KDE 4.4 >= 20090624)) kdelibs svn rev. 989682 / kdebase svn rev. 989682 on ArchLinux i686 - Kernel 2.6.30 And I think I can't reproduce neither my crash of bug 191521. (but I need more time to test it). Thanks
This crash report is at least 3 years old and there were no further comments or status updates since then. Therefore we believe that this crash is already fixed in recent KDE 4 versions or the backtrace is no longer applicable to the current KDE 4 sources. If the crash still happens with a recent KDE version (4.10.5 or 4.11), please add an updated backtrace or provide steps to reproduce. For more information, see http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports (To prevent automatic closing of this bug in the future, please set the bug status to ASSIGNED or CONFIRMED)
