I have also experienced this bug. First noticed it upon a Breezy > Dapper upgrade. Tried uninstalling (also removed ~/.mozilla & ~/.mplayer the second time) /reinstalling both packages twice.
I also noticed this on a dapper daily build [- Alpha i386 (20060228)] > Dapper install. I have not tested on a fresh install. -- Mplayer plugin doesn't work in mozilla https://launchpad.net/bugs/48424 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
