 I found that i have to install ibus.
 
 After installing ibus everything now works for me.

Going back to your original message (which I didn't see before, as this
bug was reassigned):

 on the file open dialog libre office get stuck and the whole system gets 
 frozen
 no user interaction is possible any more
 mous is moving but every otner action is no more possible
 you cant even change to console via STRG+F1

You need to use the Alt key as well.

 system is not more responding

This really sounds like LibreOffice (or more likely an extension to LO)
has grabbed and then not released the keyboard and mouse.  Applications
can override normal window focus temporarily ('grab') for purposes like
drag-and-drop, but unfortunately this is not automatically released when
you release the mouse buttons.  If an application fails to release its
grab it can effectively break the entire desktop session in the way you
described.  However, the console switching keystrokes should still work.
Could you temporarily remove ibus and test that Strg-Alt-F1 works when
the system is in this state?

Ben.

 I meant Strg-Alt-F1
 and it did not respond. 
 
 The system does not respond at all:
 even Strg-Alt-Backspace to Kill X

Well, that key combination is now disabled by default.

 or Strg-Alt-F1 to F6 did do anything.
 Everything is blocked.

OK, that does sound like something more serious than an unreleased grab.
But I cannot see what difference ibus could make.

 I think the BUG is in KDM.

I don't think so.  kdm gets out of the way once you have logged in.

Ben.

 In this log file i found the log message
 QFont::fromString: Invalid description 'Sans Serif,10,5,0,50,0'
