There is NOT a problem with ALL subtitles. If you bother to read the matroska documentation or just the error message given by mkvtoolnix you find out that only vosub, srt and ssa/ass are supported right now. Never tried with vosub at this version (never will as I just went up to the latest version). But ssa/ass are accepted. Only srt is not recognised in this 2.0.2 version. The problem with ssa/ass is that the players I have tested (vlc, mplayer, gmplayer, totem) seem unable to show them.
The bug report is wrongly stated.
