You can remove that file that causes it to be updated automatically.
But probably only doing a regression on MPlayer SVN should work.

I agree it sounds like that it is related to some MPlayer change,

However I also consider it a MESA bug, it shouldn't be crashing
but instead set some error code and return without doing anything
in the worst case.
