Summary: pix_film crashes with Apple Animation (runlength) videos

Initial Comment:
pix_film crashes when loading png-encoded videos.
I encoded them with ffmpeg using -vcodec png.

I don't know which backend is being used for decoding the video files (how can I find out?) but lqtplay plays the same files without crashing (and Gem is linked against the same libquicktime as lqtplayed, at least that's what ldd says).

on linux/osx/similar you can use gdb for producing one:
$ gdb -args /path/to/pd -nrt -stderr -lib Gem -open /my/faulty/patch.pd
[...]
(gdb) run
[... do something to trigger the crasher bug ...]
(gdb) backtrace
[...]

Message:
Sorry It's NOT PNG, it's Apple Animation codec (runlength). I was testing
several videos and I got confused.

I edited the summary but I can't seem to edit the description.

The rest of the description is correct: lqtplay does not crash, Pd does.
