breaks fate

TEST    vsynth1-prores_ks
Test vsynth1-prores_ks failed. Look at tests/data/fate/vsynth1-prores_ks.err for details.
make: *** [fate-vsynth1-prores_ks] Error 1

[...]

I seems to be lame as failed to find how to run fate to check prores_ks :(

General way to run all of FATE:

$ configure --samples=/home/path/for/samples/ --enable-gpl [...]
$ make fate-rsync
$ make fate

There are sub-targets, too, as listed in Michaels mail, like fate-vsynth1.

thanks,
just sent new patch
