There is include "cz(basic)" instead of "pc/cz(basic)" in symbols/pc/cz. This is fixed by attached patch. When I checked also other pc/* keymaps, it seems that problem is only in pc/cz keymap.
Created attachment 3824 [details] [review] Patch that corrects includes in symbols/pc/cz
Confirming the patch is working. Please include to the CVS as this bug makes XKB Czech keymaps unusable. See FC5test3 bugreport for more info: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=177362
Maybe this should be marked as "blocking" as it really makes Czech keyboard unusable.
this is fixed in xkeyboard-config
