(I disagree.)
If that were true, more time should be given for 
reviews imo.

If you cannot test, how do you know it is correct?

The palette is transparent, this indicates a bug 
somewhere afaict (not necessarily in the demuxer.)
The palette is never used because gray is signaled, 
this indicates another difficult to understand 
issue, this one definitely demuxer-related.
In any case, the patch is not a sufficient fix for 
the demuxer issue.
