Currently, if a module does not have an explicit

then, implicity, it starts with:

I, for one, would not mind if the 'module Main where' clause was
mandatory; I am not sure why or when it was made optional -- perhaps
that can be changed.

If you can reproduce the situation, definitely file a bug report at:

http://haskell.org/ghc/reportabug

Regardless of whether you can reproduce the error, you can also file
another bug suggestion that the wording of that message is
incomprehensible.

Fixing these types of bugs, and improving the error messages are both
considered important.
