            Bug ID: 306501
          Severity: crash
           Version: 2.9.1
          Priority: NOR
          Assignee: kget at kde.org
           Summary: kget stalls, then crashes after suspend resume
    Classification: Unclassified
                OS: Linux
          Reporter: squan at web.de
          Hardware: openSUSE RPMs
            Status: UNCONFIRMED
         Component: general
           Product: kget

Application: kget (2.9.1)
KDE Platform Version: 4.9.1 "release 561"
Qt Version: 4.8.2
Operating System: Linux 3.4.6-2.10-desktop x86_64
Distribution: "openSUSE 12.2 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
1) start a http download
2) schedule a suspend after expected end of download
   (with e.g. #sleep 1h; powersave -u')
3) download will stall randomly for no apparent reason
  (often kget pause and resume do not fix this and the only thing
  to resume the download is to just restart kget)
4) computer suspends at scheduled time
5) resume computer
=> kget crashes

The crash can be reproduced some of the time.

-- Backtrace:
Application: KGet (kget), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
