No problem :) I'm glad to help :)

I applied that patch recompiled xorg. Now with simple /usr/bin/X or from
KDM or from XDM keys are ok. I press key and not got segaults. But, when
i try from GDM then it segfaults still with the same error :S
XkbCopyKeymap stuff. :S (with the patch applied)

I rebuilt gdm with new patched xorg (from git) but did not helped :S

Still segfault from GDM when pressing a key. Intresting thing that GDM
fallbacks to some "generic"DM stuff (which is not kdm or xdm) and that
is works fine :S

I dunno it is a gdm or still an xorg releated problem :S 

Anything need from me ?
