I just reproduced it w/ and w/o debugging symbols under >=gnome-2.30.

I've used `setxkbmap us` and `setxkbmap us_de` (regular us w/ umlauts on the base letters).

(In reply to comment #3)
I cannot reproduce the issue here, and

>     at wmxkb_xkb.c:424
I find while(--j>=0) SymbolNames[--k] = SymbolNames[j];

which is not that useful.

I cannot neither reproduce nor fix this bug.

Michael, if you are able (and willing) to fix it, please reopen.
