           Summary: kget crashed when starting third download
           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:           v0.8.5 (using 3.5.9, Gentoo)
Compiler:          Target: x86_64-pc-linux-gnu
OS:                Linux (x86_64) release 2.6.25-gentoo-r7

In case anyone is still working on KDE-3.5.9: Yesterday I was downloading
several files [videos from akademy] (two of them active, the other ones
queued). When I resumed a third download (one of the queued ones), kget crashed
with the following backtrace as soon as I hit the "resume button":

Using host libthread_db library "/lib/libthread_db.so.1".
