I'm not sure how to reproduce this problem. But it seems there is something related to case-insensitiveness of windows file system. My best guess that for some reason there was directory named 'C1', and bzr fails when it try to create 'c1'. But I don't understand how it might happens. Bzr always creates prefixes in lowercase. It smells like something weird happens with filesystem. I'd rather change status to 'Incomplete'.
