[tlug] folding segv

[Botond Botyanszki <9915104t@example.com>]

I was trying to run the folding@example.com client (v3.24), but it segfaults
when trying to connect to the assignment server.
tcpdump shows no traffic at all, so it dies even before any network
activity would take place.

Arguments: -verbosity 9
[13:17:25] - Ask before connecting: No
[13:17:25] - User name: BOTi (Team 13160)
[13:17:25] - User ID not found locally
[13:17:25] + Requesting User ID from server
[13:17:25] - Getting ID from AS:
[13:17:25] Connecting to http://assign.stanford.edu:8080/
Segmentation fault

The strace output is attached.

If at least they'd provide the source to compile the thing.
