Sentry Crash Report:

Description squan 2012-09-09 16:27:42 UTC 
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".

Comment 1 David E. Narvaez 2013-02-21 05:01:45 UTC 
Can you elaborate on step 3 of the information above? My random guess is that this can be reproduced only when 3 happens and it may not always happen, am I right?
