Of course I can! Thanks for reminding me on this... :-)

I reproduced the problem with gdb attached and got the following 
backtrace.

(gdb) c
Continuing.

Program received signal SIGPIPE, Broken pipe.

This is very far away from my own code. This unfortunately tells me 
nothing!

Any idea how I could proceed?

Thanks a lot!
