I can confirm error message while playing a .mov file.
Additionally, after a subsequent attempt to play a .mp4 file totem crashed (crash file automatically uploaded) and crashed every time totem was started.
Starting totem by double-clicking on a file displayed in nautilus allowed the program to start normally and play videos but still crashes with some file types. May be different bug though.
