loop-nr.:0 testing KeyCode=52 -> KeySym 0x7a name=z
*** xprop -root | grep XKB
_XKB_RULES_NAMES(STRING) = "xorg", "pc105", "de", "", ""

I didn't have a look at the sourcecode of xprop but shouldn't it print out 
a 'us' instead of a 'de' keyboard layout,?
So here is a bug in either xprop or in xorg. Am I right?
