When this happens kwrite takes over 80% of CPU, so it looks like something hit 
a loop and got stuck:

Here is the top output:

16307 david     20   0 45236  19m  15m R 86.9  2.6   1:10.09 kwrite

That's 86.9% of the CPU when kwrite hangs.

Same thing happens in kate. I'll open a new bug with BLOCKER when I get back 
from lunch :(
