Bug 150152

Version:           2.1 (using KDE 3.5.6, Kubuntu (feisty) 4:3.5.6-0ubuntu14.1)
Compiler:          Target: x86_64-linux-gnu
OS:                Linux (x86_64) release 2.6.20-16-generic

KTorrent crashes daily, sometimes when I'm in it, sometimes in background.  I can't reproduce it, it seems totally random to me... as a total linux n00b.  
It always gives the message about "the signal 11 (SIGSEGV)".  Backtrace:

(no debugging symbols found)
Using host libthread_db library "/lib/libthread_db.so.1".
