Bug 280472

Application: ktorrent (3.3.4)
KDE Platform Version: 4.4.4 (KDE 4.4.4) "release 2"
Qt Version: 4.6.3
Operating System: Linux 2.6.34-12-default i686
Distribution: "openSUSE 11.3 (i586)"

-- Information about the crash:
Running on a P4 SL7PN with 768MB RAM... can't see any possible instability as ktorrent has always outperformed my expectations, especially since I seed Linux distro's at nearly 800MB/s. Any answers would be helpful.

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