When I go to http://lxr.kde.org and search for the identifier "i18n", konqueror crashes.
I tried 2 times -> 2 crashes.

konqueror from trunk as of today also crashes.

I do not exactly what to write here to make the bug reporting assitent happy,
I just wanted to add the backtrace from trunk.

Hopefully this is now enough text.

This could be related to bug 202499 or bug 187742
Comment 3 Anne-Marie Mahfouf 2010-01-28 21:04:06 UTC 
I get the same backtrace from http://xmpp.org/extensions/xep-0136.html
I ran Konqueror through gdb to get the backtrace
