Comment 4 for bug 670159

Aaron: While I agree bzr can't reasonably make use of a malformed patch like this one, it shouldn't crash out with StopIteration. A traceback from the CLi is always a bug.

Chris: What command did you run? Would you mind posting the traceback to this bug? It's not clear from your bug report how you encountered this situation, as bzr itself doesn't handle plain patch files directly. (I can speculate that it might involve corrupted shelves or merge directives, but rather than guess I'd rather be sure I know what your problem is.)
