I think it is not useless.  It says exactly the same as I did, in another 
reply:  git blame starts with your working tree.  As such, it has to do 
some operations which happen to fail on unmerged files.

So the solution in your case _really_ is:

	git blame HEAD file2

Explanation: with that command line, you ask git blame to start with a 
given revision (instead of the working tree), which just so happens to be 
the HEAD revision.

Hth,
