Description Paul Barbee 2009-05-08 09:17:06 UTC

Version:            (using KDE 4.2.2)
OS:                Linux
Installed from:    Ubuntu Packages

If WebKit has been made the default view mode and you try to go to View>View Mode and change the view mode to KHTML Konqueror immediately crashes.

Comment 1 Paul Barbee 2009-05-08 09:18:40 UTC

Data from BugBuddy follows:

This backtrace appears to be of no use.
This is probably because your packages are built in a way which prevents creation of proper backtraces, or the stack frame was seriously corrupted in the crash.

Comment 2 Dario Andres 2009-05-08 15:32:20 UTC

The crash seems to be inside deep Qt WebKit code. If you can reproduce at will , can you install "libqt4-dbg" and "libqt4-webkit-dbg", to get a better backtrace?
Also, what is your Qt4 version
Thanks

Comment 3 Dario Andres 2009-06-12 16:28:19 UTC

Marking as NEEDSINFO

Comment 4 Dario Andres 2010-11-18 14:53:09 UTC

[Comment from a bug triager]
Moving old kdewebkit bug reports to kdelibs/kdewebkit. Sorry about the noise

Comment 5 Dawit Alemayehu 2010-11-18 20:58:32 UTC

This bug or rather the source of the bug should have been fixed a while back. If you still experience this problem, please feel free to reopen this ticket with the extra information requested in comment #2... Thanks for the report.
