hmm, both Gem (i tried 0.93.git:ee897d5 and 0.93.3 from Debian) and
gmerlin (1.2.0~dfsg-3 from Debian) can play the file just fine here.

if i just call it with `gmerlin_play` i get:
$ gmerlin_play crashme.mov
[avdecoder.audio_ffmpeg] Warning: Codec not found: FFmpeg Sonic decoder
[avdecoder.superindex] Info: Detected B-pyramid, fixing possibly
broken timestamps
Segmentation fault

you could also just deinstall the GMERLIN-backend (if you don't need
it for other stuff). since PdX gives you an all or nothing, you'd had
to remove (or rename) the "gem_filmGMERLIN.so" file.

ah yes,
and the fps is reported as well, though that's not mentioned at all.
