Version: (using KDE 4.1.2) OS: Linux Installed from: Ubuntu Packages $ konqueror QObject: Do not delete object, 'unnamed', during its event handler! ASSERT failure in QList<T>::operator[]: "index out of range", file /usr/include/qt4/QtCore/qlist.h, line 401 KCrash: crashing... crashRecursionCounter = 2 KCrash: Application Name = konqueror path = <unknown> pid = 10597 sock_file=/home/alan/.kde4/socket-alan-desktop/kdeinit4__0 I hope this backtrace PLUS the assertion message is a little less woolly and more useful than my description :-). I've had this happen twice. Once I was browsing the Register, opening multiple articles in tabs. The second time, it was just after opening a second tab; the first tab was "man:select" and the konqueror instance had just been session-restored after logging in. It's related to opening new tabs. Just before the crash happens, the information on the tabs becomes inaccurate. In the last case, I think I opened a new tab, visited something, switched back to the first tab - and then the title on the second tab vanished. In the first case, when I was using ctrl+> to flick through tabs, the titles changed as I did so (maybe the titles shifted left or something). It may be related to "split view" as well. Sometimes I press ctrl+shift+T and split the view, when I meant to press ctrl+T and open a new tab. (Backtrace for the assertion follows).

*** Bug 175501 has been marked as a duplicate of this bug. ***
As I already wrote in the duplicate report, I could not reproduce this so far in Konqueror 4.1.3 (Kubuntu). If you find a way to reproduce this crash reliably on some particular site or with a special setup (like a special number of tabs open, split views), please post a link/a detailed description how to reproduce this here. Also a better backtrace might help, see http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports Thanks for your help!

I think this is the same bug as Bug 177036, which got fixed after 4.1.3 too. KTabWidget was getting confused, it's quite likely that in addition to setting the wrong text on the wrong tab, it could also go out of bounds and crash. Please reopen if you get this crash again in 4.2. *** This bug has been marked as a duplicate of bug 177036 ***
Bug 191508 seems to be related to this but in KDE4.2.2 (?)
