dirstate AssertionError after auto rename

I have the following directory structure:
images>some_images
images>originals>some_other_images
only few of the images are versioned (only .svg files). i moved two .svg files from images to images/originals by hand (not using bzr commands) and after that ran bzr mv --auto.
This generated a lot of hash hits and displayed something like images => images/originals. after that i got the error on almost all operations (except log, info...).

Wouldn't it be better if --auto asked for confirmation by default, without having to --dry-run first?
Cheers, Sebastian
