Sentry Crash Report:

Description Joachim Mairböck 2012-06-22 18:45:55 UTC 
Application: konqueror (4.8.4 (4.8.4))
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.2
Operating System: Linux 3.1.10-1.9-pae i686
Distribution: "openSUSE 12.1 (i586)"

-- Information about the crash:
- What I was doing when the application crashed:
While trying top reproduce something from Bug 246736 using http://www.gtalbot.org/BrowserBugsSection/Konqueror4Bugs/Bug246736-Play-Flash-Videos-YouTube-iframe-with-embed.html Konqueror crashed when closing that tab (from another tab) after having started the video and paused it.
- Unusual behavior I noticed:
The video hangs and doesn't play, just the audio is hearable and there is a high CPU usage after trying to play the video (see Bug 246736#c15).

-- Backtrace:
Application: Konqueror (kdeinit4), signal: Aborted

Comment 1 Joachim Mairböck 2012-06-22 18:56:10 UTC 
Bug 246736 has nothing (directly) to do with HTML5, so the experienced hang is probably different.
Comment 2 Gérard Talbot (no longer involved) 2012-06-22 19:16:16 UTC 
Joachim,

You were using: 
Konqueror 4.8.4 (using KHTML rendering engine)
Flash Player 11.2.202.236 (from official repository)

I have updated Version field, URL field, Keywords field of this bug report.

I can not confirm your bug as I did not so far crash.

Gérard

Correct, but in this case there was no Flash involved.

I am using phonon 4.6.0, which is used here, with the gstreamer backend.
Comment 4 Myriam Schweingruber 2012-06-25 08:25:37 UTC 
The crash is most likely upstream in libgstreamer, I doubt Konqueror is to blame.
