           Summary: kget crashed when selecting several downloads from list
           Product: kget
           Version: unspecified
          Platform: unspecified
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kget at kde.org
        ReportedBy: Regnaron at web.de


Version:           2.1.1 (using 4.1.1 (KDE 4.1.1), Gentoo)
Compiler:          i686-pc-linux-gnu-gcc
OS:                Linux (i686) release 2.6.25-gentoo-r7

Today I downloaded two files with kget. After both downloads were finished, I
selected the first one by clicking on it (it expanded) and then selected the
second one by hitting shift+down. KGet from KDE-4.1.1 then crashed with the
backtrace below. Regrettably I am not able to reproduce this crash.

Application: KGet (kget), signal SIGSEGV
