Bug#520149: vlc segfaults in malloc() when reading subtitles

Package: vlc
Version: 0.9.8a-2
Severity: normal

Hey,

it seems that vlc now segfaults on each and every video when using
subtitles file. I've attached an example .srt which exhibits the crash
(with the first video I found on youtube)

It works if I disable the subtitles autodetection.

Cheers,
