           Summary: kget crashes after resuming a paused transfer
           Product: kget
           Version: unspecified
          Platform: openSUSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kget at kde.org
        ReportedBy: squan at web.de


Application: kget (2.4.2)
KDE Platform Version: 4.4.2 (KDE 4.4.2) "release 238"
Qt Version: 4.6.2
Operating System: Linux 2.6.31.12-0.2-default i686
Distribution: "openSUSE 11.2 (i586)"

-- Information about the crash:
After performing the following steps kget crashed:
1) Stop a (single) transfer
2) log out from KDE
3) start new KDE session
4) start kget and resume transfer

The resumed transfer started from the beginning (already downloaded data lost).
I guess that this can not easily reproduced.


The crash can be reproduced some of the time.

 -- Backtrace:
Application: KGet (kget), signal: Segmentation fault
