Just to notify you David,

the port is still too unstable for me, and I have to spent some time on my 
GSOC. I won't be able to do more in that regard until after GSOC. I've again 
wasted quite a lot of hours trying to fix things.

Sorry, I hope my reports where at least useful and that you are able to fix 
them. I'll definitely work on that again after GSOC.


PS: just for the protocoll, here are the most annoying bugs that I hit all the 

- crash on document reload (see long thread on kwrite ml)
- deadlock on assistant (see this ml)

And I generally percieve it to be "slower", i.e. more sluggish. Looks like 
I'll have to do a lot more profiling after GSOC ;-)
