Yes, well tracked down Ronald. Looking into the code while working on
the fix, I think I can now explain where the negative values were
coming from. There's a pyrex extension module that uses the platform
lstat directly then wraps the result to look like a normal Python stat
result. With the following, I get some negative values:

    from bzrlib._readdir_pyx import UTF8DirReader
    for r in UTF8DirReader().read_dir(".", "/cygdrive"):
        print r[4], r[3].st_dev

Based on your earlier feedback I've already included a test for
negative st_dev values with the fix, which is proposed for merging
now:
