Description Paul 2011-03-21 22:24:31 UTC

Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.1 (KDE 4.5.1) (Compiled from sources)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-28-generic-pae i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed: I was watching NJR paris live TV (which uses flash player 10.00). I was using firefox as a browser.

- Unusual behavior I noticed: When I used microsoft I would go to the site, click on the TV (flash) and then enlarge to full view, which would cover my entire screen. On Kbuntu everthing went OK until I tried to the entire screen. In this case the flash video would dissappear and I would be left with the browser opened on the right page minus the video. I could still hear the voices. I then gathered that the full -screen video was behind the browser window. So, as I would have done on windows I reduced the bowser to Icon but:  1. The flash video dissappeared, though the audio remained. 2. The browser icon was nowhere to be seen.   After repeating the experiment a few times I decided to change browser and use the default one. At this point the crash happened. .....................???where do the icons go when you reduce a broswer to

the full screen flash crash is a bug in flash (seems to be triggered by certain new video drivers, e.g. the current stable intel driver), the crash in plasma-desktop happened in Qt.
