Comment (by raptor399):

 Sorry for posting this ticket just before my holiday and only getting back
 so late!

 Thanks for all the useful feedback, it helped me greatly on my search for
 a solution.

 As it turns out, FFmpeg is working just fine. Fontconfig could not find a
 configuration file and when it did, that file did not contain any real
 font paths.
 I have verified this with the ffmpegexperts OSX build and the latest
 snapshot build.

 I did two things to get fontconfig working properly on my system:

 - export FONTCONFIG_PATH=/opt/X11/lib/X11/fontconfig
 - edit the /opt/X11/lib/X11/fontconfig/fonts.conf and added the directory
 "/Library/Fonts" to the font directory list

 After this subtitles are burned in as expected, with both "-vf
 subtitles=..." and "-vf ass=...". Even if fonts are reported missing by
 fontconfig, a substitute is used and the subtitles are still being burned.

 Please close the ticket, as the problem is indeed caused by fontconfig
 configuration as people suspected.
