After upgrading to Noble, totem throws data stream error when going fullscreen

[Wise Ferret]

After upgrading from Mantic to Noble, totem throws "data stream error" message when going fullscreen while playing mkv files and stops playing.
vlc works fine. I use the latest nvidia proprietary driver (550).

This is what I get in the terminal with debug level of 2:

In Mantic same file played well. ubuntu-restricted-extras is installed, gstreamer-vaapi is installed. Any ideas about what is going on?

Sounds like a bug against totem, and Noble of course is still very wet behind the ears. (But you knew that)
