Sorry, I think this is a duplicate of 1969512 (marking as such) -- I have found, in the course of investigating that one that we may either need to switch the ISO test to use an OGG (or OGV) file instead (or mandate that gstreamer1.0-libav is installed first) but the bug still stands (even with that pkg installed, totem's reporting the same message).
