Subtitle test files.

Overview:
If a .srt file is manually loaded for a playing video, any html-style tags in the subrip file are either recognized (for instance, italics) or fail gracefully (for instance, font color tags). However, if the same .srt file is merged with the original video into a Matroska file, tags in the subtitle file are displayed literally instead of being interpreted.

Steps to reproduce:
1. Play a video file a and load a subrip file that uses tags (e.g. <i>, <font color=...>, etc) in totem. Observe that tags are interpreted or silently ignored.
2. Merge video and subtitles with mkvtoolnix-gui.
3. Play resulting Matroska file with totem.

Actual results:
Tags are displayed along with subtitle text.

Expected results:
Tags should handled exactly as when loading an external .srt file.


Problem occurs on Totem 3.0.0 with GStreamer 0.10.34 on a debian unstable + experimental system. First noticed problem with unstable version of Totem, upgrading to experimental version changed nothing.

Attached are some files that demonstrate the problem.
