Bug#275046: fixed with version 2.2.1-5

[Nadav Kavalerchik <nadavkav@netvision.net.il>]

i've added a new user "adduser foo" (as suggested)
logged in, (default was GNOME desktop) open Impress
inserted a video (avi file) with no problem :-) it played.
i also check several other videos with different encoding
methods, all worked fine.

BUT, a new bug surfaced... 
the video was playing in a new window it was not embedded in the 
Normal edit view and also while playing the presentation it would jump off
into a new window when the presentation's slide was displayed.
it only happened in GNOME , in KDE it worked fine (embedded inside the 
presentation )

i'll open a new issue for that.
