Bug 244086

Application: ktorrent (4.0.1)
KDE Platform Version: 4.4.4 (KDE 4.4.4)
Qt Version: 4.6.3
Operating System: Linux 2.6.34-12-desktop x86_64
Distribution: "openSUSE 11.3 (x86_64)"

-- 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
