Well, here is how to reproduce.
0. Ensure that Xserver is configured to support english/russian keyboard.
We use followinf lines in /etc/X11/XF86Config-4:
...
Option "XkbLayout" "us,ru"
Option "XkbOptions" "grp:menu_toggle,grp_led:scroll"
...
1. Start konqueror
2. Open http://ya.ru/
3. Create a new tab (e.g. from menu)
4. Open http://ya.ru/ in the second tab
5. Switch keyboard to russian more (in the above config - by pressing
"Menu" key)
6. Press Ctrl+W
And it crashes.
The http://ya.ru/ is not the only site that causes the crash; many do. We
used this one while debugging because with it, crash was 100%
reproducable.

I'm duplicating suggested workaround here:

return false;
if( pEvent->type == XKeyPress ) {
+ unsigned int tmp = pEvent->xkey.state;

KKeyNative keyNative( pEvent );
+ pEvent->xkey.state = tmp;
KKey key( keyNative );
key.simplify();
int keyCodeQt = key.keyCodeQt();
I don't think it's a real fix, it's just a workaround that forces kaccell
code to assume english keyboard layout while searching for accelerator.
However, this looks harmless (because accelerators should be independent
of current keyboard layout, and nothing other that accelerator search is
affected), and this really stops that crashes.
