Hello again,

I tried to get a coredump with the infromation an the provided web-page. 
However i never got a dump. I used the packages provided by "deb 
http://xi.rename-it.nl/debian/ testing-auto main". I don't know if these 
contain the debugging symbols. So it seems i can't provide any further 
information.

Regard, Tom
