          Severity: crash
           Version: unspecified
          Priority: NOR
          Assignee: joris.guisson@gmail.com
           Summary: Ktorrent (only) Crashes at start up
    Classification: Unclassified
                OS: Linux
          Reporter: phonic_p@tpg.com.au
          Hardware: Ubuntu Packages
            Status: UNCONFIRMED
         Component: general
           Product: ktorrent

Application: ktorrent (4.1.3)
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-24-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed: downloading torrent file with
Fire Fox then attempting to open it with k-torrent to begin download but the
Window was all greyed out except the title bar. I tried to close but it
wouldn't. until the kubuntu pop up window asked if I wished to terminate
K-torrent, I selected yes. then tried to re-open it, no luck just a crash
window now.  So I rebooted and tried again , stil no luck then uninstalled and
rebooted then reinstalled but still no luck.

-- Backtrace:
Application: KTorrent (ktorrent), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
