Patch looks ok, however, my current cvs tree is messy as i am working on 
several uncommitted things too, so I can't apply right now, and your 
patch has changes in various directories. Maybe Marc (or Mattias of 
course but he seems to be offline)?

Note that I have seen your other memleak patch but I can't judge the 
code because I know nothing about that part of the codebase. I will 
apply it if nobody objects in a few days.

Regards,

Micha.
