Bug#478971: vlc: wrong length computed for matroska videos, video skips

Package: vlc
Version: 0.8.6.c-6+lenny4, 0.8.6.e-2.1
Severity: normal
Since 0.8.6.c-6+lenny4, when I open matroska (.mkv) videos, the status
bar in vlc shows an incorrect length for the movie. Shortly
afterwards, instead of starting playback, the current time is shown as
negative numbers (e.g. similar to -2:-34:-15) and seemingly random
screenshots from the movie are shown. Playback is practically
impossible.
This happened with every matroska movie I have tried so far (xvid and
H.264, with and without subtitles).
The following is the console output for one of the sample movies from
http://www.matroska.org/samples/
$ vlc starwars10MB-1.mkv

[00000378] main decoder error: no suitable decoder module for fourcc `undf'.
VLC probably does not support this sound or video format.
[00000281] main playlist: nothing to play
[00000281] main playlist: stopping playback
(I closed vlc between the last two lines).
I have also tested 0.8.6.e-2.1 and it suffers from the same problem.
Immediate previous revisions are fine (good playback and no messages
like above in console output). In summary:
0.8.6.c-6+lenny3: ok
0.8.6.c-6+lenny4: bugged
0.8.6.e-2: ok
0.8.6.e-2.1: bugged
