RXP, I agree. It seems unnecessary to use VSFilter when ffdshow can do the job (and also decode video/audio if desired).

What you need to do is add ffdshow raw video filter at Movie Post Processing in MediaPortal Configuration. Now you can watch .mkv:s with embedded subtitles and if you want them displayed, enable Subtitles in ffdshow Video decoder configuration.

I guess this is some kind of bug in MediaPortal. It would be nice if the movie launched without subtitles if no filter can handle it instead of MP crashing. If anyone is interested here's what the log file says when that happens:
