Affects: totem (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
I'm using Totem 1.4.0-0ubuntu2 on Dapper, with the default Gstreamer
backend.

When I play an AVI file, the associated SRT subtitles play
automatically. When I disable the subtitles with View > Subtitles >
None, Totem crashes.

However, it doesn't crash immediately. The video keeps playing, but the
rest of the interface is unresponsive (the slider stops moving, time
doesn't update, buttons don't highlight, etc.)

In this unresponsive state, one more subtitle is shown. When it is time
for that subtitle to disappear, Totem shows an "Internal data flow
error." and stops playing the video. At this point I can't do anything
except close Totem.

This problem doesn't occur with the Xine backend.
