lottanzb not stable on natty, crashes from time to time

[gehrts]

I run Natty w/o unity on a 32bit intel.
lottanzb, is not running stable. It crashes always.
Sometimes it dies immediately, sometimes it stays for some time... like 10 minutes or so... and crashes again. Here is what I get when it dies (started via gnome-terminal):

10:28:39 lottanzb.core LottaNZB 0.6 wird gestartet...
10:28:39 lottanzb.backend Verbindung zu ' localhost:8080' hergestellt.

Is that a phyton or a lottanzb problem?
