#31 Dereferencing NULL pointer

[Johan Gade]

Whenever I run OpenAG X 1.1.1 cvs 1.38 it will try to dereference a
NULL pointer after a little while (sometimes I succesfully started
recieving a file before it happens). It happens both when I have
shares selected off and when they are on in the preferences.

Below is the output of a run with gdb with shares off:

Please write me, if you need more information (as you can see from
the ip adress I am on a local subnet, but I do not think it's relevant
here.) :
