Application: konqueror (4.5.3 (KDE 4.5.3))
KDE Platform Version: 4.5.3 (KDE 4.5.3)
Qt Version: 4.7.0
Operating System: Linux 2.6.32-25-generic i686
Distribution: Ubuntu 10.04.1 LTS

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

Thought it might be worth reporting this since it appears to involve the html rendering process, and since KHTML seems to be affected, but the WebKit part is not.

1. open the following in konqueror: https://docs.google.com/present/view?id=dzq234z_27dctvfwf5&browserok=true
2. select "Play" from the "Actions" menu at the bottom of the window
3. at the end of the presentation, it crashes reliably.

This happens for some other google docs presentations, as well, but this one above is short. I tried creating a simple empty 2-slide presentation on my own, but playing that one doesn't cause the crash in KHTML, so it appears that it's nothing special about the final "presentation finished" page it takes you to at the end.

Note that the presentation appears differently under WebKit vs. KHTML, in that the images on the first few pages appear only in WebKit, but the embedded video player on one of the later pages appears only in KHTML.

The crash can be reproduced every time.
