This looks like a DHT problem in libtorrent-rasterbar. Please report this bug (with the backtrace) there:
http://code.google.com/p/libtorrent/issues/entry

In the meantime, you should still be able to run qBittorrent if you disable qBittorrent. To do so, here are the instructions:
edit ~/.config/qBittorrent/qBittorrent.conf

and change line:
Bittorrent\DHT=true

to read:
Bittorrent\DHT=false

Excuse my ignorance but where and how exactly do I do this?
I am quite new to Ubuntu (9.10) and trying to learn.

Thank you for your help.

To edit the file, type the following in a terminal:
gedit ~/.config/qBittorrent/qBittorrent.conf

Then find line:
Bittorrent\DHT=true

Simply write false instead of true to disable DHT.

Save and close the file.

Start qBittorrent.
