Description Harisankar Krishna Swamy 2012-02-26 07:44:02 UTC

Application: kget (2.7.2)
KDE Platform Version: 4.7.2 (4.7.2) "release 5"
Qt Version: 4.7.4
Operating System: Linux 3.1.9-1.4-desktop i686
Distribution: "openSUSE 12.1 (i586)"

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

I was downloading Hadoop from Apache website and also was downloading a tutorial video from youtube (defcon video) using plugin flashgot. The plugin in firefox is configured to use kget as download manager. While downloading the video, I noticed that there were multiple videos being downloaded (probably different versions or other video linkss in the page). So i decided to cancel the rest of the download in kget. When I removed one of the videos from the bottom of the list kget crashed.

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

Comment 1 Matthias Fuchs 2012-02-26 11:09:47 UTC

Thank you for reporting this issue.

Can you please install debugging packages [1] and retry to crash KGet?
This will help in finding the problem.

Other than that. What did you choose in flash got? "FlashGot Media"?
Further please list the version of FlashGot and Firefox.

Greetings,
matthias

Comment 2 Harisankar Krishna Swamy 2012-02-26 19:08:18 UTC

ok. tried to recreate the bug.

1) I installed kGet debugging package from opensuse.

2) I go to the youtube video, use flashgot to download the video, same as before there were a couple more links for the single video. 

3) I remove the duplicate ones from kGet and it does not crash but, hangs. the kGet application does not respond from then on. When I close it with the x button, a "not responding terminate window is shown".

4) At one retry, the whole computer just froze. But, the video was still going. Was not able to switch to other applications etc.

But, kGet does not crash as the first case now. 

Best Regards,
- Hari
