           Summary: ktorrent crashes when the computer is otherwise idle
           Product: ktorrent
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: joris.guisson@gmail.com
        ReportedBy: art.alexion@verizon.net


Application: ktorrent (4.0.1)
KDE Platform Version: 4.4.90 (KDE 4.4.90 (KDE 4.5 RC1))
Qt Version: 4.7.0
Operating System: Linux 2.6.32-23-generic-pae i686
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:

Nothing.  This only seems to happen when I am not actively using the computer.

- Unusual behavior I noticed:

If ktorrent is minimized to the tray, the crash reporting assistant doesn't
start.



- Custom settings of the application:

Before I install the debug package, the crash reporting assitant always started
when ktorrent crashed.  Now, it only starts if ktorrent has focus during the
crash.

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