I meant Strg-Alt-F1
and it did not respond. 

The system does not respond at all:
even Strg-Alt-Backspace to Kill X
or Strg-Alt-F1 to F6 did do anything.
Everything is blocked.

I think the BUG is in KDM.
In this log file i found the log message
"QFont::fromString: Invalid description 'Sans Serif,10,5,0,50,0'
