           Summary: Kget crashes when downloading repeatedly
           Product: kget
           Version: unspecified
          Platform: Debian unstable
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kget at kde.org
        ReportedBy: rasasi78 at gmail.com


Application: kget (2.4.4)
KDE Platform Version: 4.4.4 (KDE 4.4.4)
Qt Version: 4.6.3
Operating System: Linux 2.6.34 x86_64
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
I chose a picasa album and started to download pictures one after another. Kget
crashed. According to the possible dupe this may be a bug in kdelibs.

The crash can be reproduced some of the time.

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