MKV files display subtitles, despite the metadata requesting otherwise

[Volodya]

I have Matroska files with the subtitles in them. The subtitles are clearly marked as not playable by default (unless chosen). The extract from the mkvinfo is:

| + A track
| + Track number: 3 (track ID for mkvmerge & mkvextract: 2)
| + Track UID: 2415072177
| + Track type: subtitles
| + Default flag: 0
| + Lacing flag: 0
| + Codec ID: S_TEXT/UTF8

As you can see default flag is 0.

What happens:
Subtitles begin to display when the file is played, i then am forced to turn them off.

What i expect to happen:
Totem should respect the flags set in the Matroska metadata and only display by default that which should be displayed by default.
