Comment 2 FiNeX 2008-05-20 21:51:32 UTC 
Are you using kwin4?
Comment 3 Henrik Skov Midtiby 2008-05-20 22:27:05 UTC 
When I found the bug I was using konqueror in the gnome desktop environment. I will try to reproduce it tomorrow in the KDE environment.
Comment 4 FiNeX 2008-05-20 22:56:25 UTC 
thanks Henrik
Comment 5 George Goldberg 2008-05-21 02:22:10 UTC 
@FiNeX:

I reproduced this issue within KDE4 (with kwin4 running), However, this is about switching tabs within konqueror using Ctrl+Tab, so I cannot see how kwin has anything to do with it.
Comment 6 FiNeX 2008-05-21 09:07:34 UTC 
I've asked because CTRL+Tab is usually binded to the "switch desktop" which is a window manager function. :-)
Comment 7 Henrik Skov Midtiby 2008-05-21 10:54:20 UTC 
The bug is there when konqueror is active in a KDE environment.

I checked if the <crtl> + <tab> shortcut was set in Settings -> Configure Shortcuts. It was not. If I set the shortcut for "Activate Next Tab" to <crtl> + <tab> it works as expected (the next tab is shown). If the shortcut is set back to the default value <crtl> + ], konqueror will crash when I push <crtl> + <tab>.

Maybe <crtl> + <tab> is hardcoded somewhere in konqueror?
