Are you using a version of file(1) that is at least from 'stable'
(I have 4.12-1). Are these errors crashing amavisd-new?

What other errors are there (if any) that are related to this message?
Are we seeing the complete picture? Is the evidence preserved where
it may be tested on another system?

I could be wrong but I'm thinking if these do not crash amavisd-new
then this is mostly an annoyance that may likely be solved by upgrading
amavisd-new. These may provide food for thought:

This post has a suggestion also, but I question whether Sarge in
particular has an issue with this, and while the workaround mentioned
would probably work, whether it is the best way to fix the situation.

I wonder if installing file(1) from testing may offer any relief.
