This is a leftover debug statement and it is a good thing. It means your
back-and-forth nametrans resolve to the same name :-). It also means you
are on the next branch on a commit older than
b92e453f0ea7c26c5eceebfb45083338564281e6 where this debug statement was

(it slipped in accidentally, I usually don't include stuff like this in
the code, sorry)

b92e453 also still contains a bug. which leads to wrong name
resolution. The fix is in commit b0e88622c4 as a response to yours and
Jon Wiegleys error reports, so you should be trying at least this
one. Ideally, you go directly to current next's HEAD which also honors
the remote folderfilter when determining whether to create a new folder

Are you saying that you do see these warnings on the current next HEAD?
And you still see that "bogus" already exists warning?
