-- Information about the crash:
Well,
this time I was not at home when it happends. In regular ktorrent crashes after some hours of run.
This is the first time that kde crash report starts.
I had only one torrent running(a self made) and not much connections.
VHT is running.
May be this helps.

 -- Backtrace:
Application: KTorrent (ktorrent), signal: Segmentation fault
