I have no idea of why the rename is failing, it must be a problem with
sshfs, here's what I tried in the console:
samuel@HOMER:~/BENCH/test/silence$ nano test.txt
samuel@HOMER:~/BENCH/test/silence$ touch bla.txt
samuel@HOMER:~/BENCH/test/silence$ mv bla.txt test.txt
mv: ne peut déplacer `bla.txt' vers `test.txt': Opération non permise
[can't move bla.txt to test.txt]
samuel@HOMER:~/BENCH/test/silence$ cd ..
samuel@HOMER:~/BENCH/test$ cd ..
samuel@HOMER:~/BENCH$ touch test.txt
samuel@HOMER:~/BENCH$ nano test
samuel@HOMER:~/BENCH$ nano test.txt
samuel@HOMER:~/BENCH$ touch bla.txt
samuel@HOMER:~/BENCH$ nano test.txt
samuel@HOMER:~/BENCH$ mv bla.txt test.txt
samuel@HOMER:~/BENCH$

silence is in a sshfs mountpoint, BENCH is in my home mountpoint.

Anyway, here's a wonky-really-crazy "patch" I made, don't tell me I'm mad
for doing this, I already know.

Replace line 164 of current version of ROX-Lib2/python/rox/saving.py
                                os.rename(tmp, path)
by
                                tmp2 = 'tmp2-' + `random.randrange
(1000000)`
                                tmp2 = os.path.join(parent_dir, tmp2)
                                os.rename(path, tmp2)
                                os.rename(tmp, path)
                                os.unlink(tmp2)

I know it seems crazy, but it's a proof of concept that at least makes
Edit useable, but I'm sure that any python gurus will scream at me when
seeing this, this must be a really ugly hack...

Now, I'm off searching the sshfs mailing list or at least contact
someone, as it may seem that the problem isn't on your end...
