Bug#818134: [totem] totem: playing the same file only sometime the video starts

[derfel]

Package: totem
Version: 3.18.1-2+b1
Severity: normal

When I play a .mp4 file with totem I can hear the audio correctly but
the video remains black and the time indicator remains fixed to
0:00:00.

If I close totem and I relaunch it with the same file after one or more
tries it starts showing correctly audio+video.

I've attached a strace log for the 2 mentioned cases.

If you need any additional info ask me.

Vlc and other players doesn't show the same bug.
