browser window closes when fullscreen video playback finishes

The bug occurs in Firefox+VLC browser plugin when I play a video. When the video is running in fullscreen while the title ends, the whole browser window (from which the video originated) is closed.

The weird thing is that the window including all tabs are closed, but other Windows from the same Firefox instance are not closed. Also I tried a few different nightlies and the oldest I tried didn't seem to have the bug yet.

I tried under Windows XP+Firefox 2+VLC 0.9.0 nightlies with file:// and dvdread:// as protocol. I used the following nightlies to test:

vlc-0.9.0-svn-20070514-1701-win32 - has the bug

vlc-0.9.0-svn-20070526-0000-win32 - has the bug

vlc-0.9.0-svn-20070312-0000-win32 - doesn't seem to have the bug
