[packman] No rendering with kdenlive 0.8.2.1-1.28 and mlt 0.7.8.1.1

[re at comunica2.net]

These are at the moment the most recent versions and rendering whatever 
format, fails. No downgrade is possible so I'm stuck now (I don't want 
to compile).

I have reasonably well working combination of kdenlive 0.8.2.1-1.27  and 
mlt 0.7.6-2.2 on another computerat least allowing me to render. But on 
the first computer I cannot downgrade to these versions because they 
have been removed from the repository.

Since the kdenlive mlt combination apparently is highly unstable, why 
not keep some older versions of both in the repository, those known to 
be working, like the versions mentioned before?
