That message is written out in two parts (ie. there are two write(2) calls): 
"su: " and "you .." Depending on the relative timing between the su process 
and kdesu, those two chunks may be read separately, or as one chunk. If they 
are read separately, then "su: " matches the regexp and kdesu assumes it's a 
password prompt.

Anyway, back to the ol' drawing board.
