           Summary: KGet crashed after failing to verify an MD5 hash
           Product: kget
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kget at kde.org
        ReportedBy: amrecio at gmail.com

Application: kget (2.7.3)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-14-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:

I was downloading a number of files for which I entered their MD5 hash. When a
file wasn't correctly downloaded, KGet asked if I wanted to download it again.
Answering "yes" made KGet crash (and lose the pending file list, which was
annoying).

I tried several times and I was able to trigger the crash several times.

The crash can be reproduced some of the time.

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