           Summary: Kget crashes on large file
           Product: kget
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kget at kde.org
        ReportedBy: m.wege at web.de


Application that crashed: kget
Version of the application: 2.3.1
KDE Version: 4.3.1 (KDE 4.3.1)
Qt Version: 4.5.2
Operating System: Linux 2.6.30-02063003-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
Kget crashes for me on downloading
http://debian.tu-bs.de/project/sidux/release/sidux-2009-02-aether-kde-full-i386-amd64-200907141427.iso

I assume it may be the size of the file, which causes the problem, because
smaller files work. I notice that Kget uses over 700mB of memory, the system
slows down (swap is big enough, should handle it).
