Comment 15 for bug 2003388

> I have found the source of the problem though. It seems as though during my upload, that file did, in fact, sneak in [3], but why it didn't show up in the debdiff, I'll never know.

FWIW, the debdiff is blind to symlinks. For example, if you make a change to file that is symlinked from elsewhere in the same package, then debdiff will present that as both files changed. Similarly, if a file is dereferenced and replaced by an equivalent real file, debdiff won't see that. So debdiffs don't round trip correctly in the case of symlinks. This makes use of debdiff to perform reviews dangerous, too.
