I did talk to two vlc upstream developers, and they told me that
libebml is kind of a mess that got recently pretty much overworked in
current vlc.git. There is a good chance that vlc 2.1 will have a fix
for that.

My suggestion at this point would be to get in touch with the vlc
developers about this. In fact, I've already done so and provided the
link to the sample; here is his answer:

16:03 <j-b> I will download, fix and backport for 2.0.6

So if we are lucky, a fix might soon turn up in debian/unstable.
Unfortunately because of the freeze, it is unlikely to land in wheezy.
