Good catch!

Sounds like a task for lintian to check for.  Please consider filing a 
wishlist bugreport against lintian for adding such check.

Maybe you could also raise the issue at debian-devel mailinglist, as 
this kind of flaw isn't specific to multimedia and others might have 
clever ideas on how to cross-check and weed out most possible of such 
flaws.
