log_tree_diff: die when we fail to parse a commit
We currently call parse_commit and then assume we can dereference the resulting "tree" struct field. If parsing failed, however, that field is NULL and we end up segfaulting. Instead of a segfault, let's print an error message and die a little more gracefully. Note that this should never happen in practice, but may happen in a corrupt repository.
