Do you see something like these output when it happens? If that is what
is happening to you, then it is perfectly normal, and the command even
gives explanations on what it did to you. The only thing you need to do
is to read them ;-).
$ git merge lt/pack-object-memuse

Automatic merge failed; fix conflicts and then commit the result.
Notice the last set of lines "Resolved '%s' using previous resolution."
Another possibility is the common ancestor of the two branches did not
have the file in question and you added the same file on each of these
branches in a non-conflicting way. That sometimes suggests a bad
workflow, but in an environment where two people independently pick up the
same patch on their branches and you end up merging with these two people,
it is also perfectly normal.
