[Samba] Time capsule and "bad smb"

Some update to the mail below: if I understand correctly, there are two
different problems showing up:
1) mount.cifs and the Time Capsule (I have no idea on which front the
problem is) don't seem to be able to handshake correctly if the share
name contains whitespaces. I didn't notice at first glance, but then found
some "no such share" errors in dmesg - not reported as output of the
command. Then I tried to change the share name (on the Time Capsule,
obviously) to a single word and reconnect, and it worked (almost, keep
2) on some particular smb commands - please bear with me if what I say
is somewhat imprecise - the Time Capsule sends back packets badly
formatted (or that mount.cifs thinks are badly formatted). This happens,
- for some packets that report an error, such as the "no such share"
- for some packets during the unmount
This is the reason why - as far as I can conjecture - though the
handshaking failed because the name of the share could not be resolved,
I didn't get a message about that: in the communication where the Time
Capsule said "hey, I don't have that share!", some packet was reported
as incorrect and dropped.
Notice that now it does mount immediately, but when I unmount it takes
almost a minute, and in dmesg I get:

Googling, I found a very similar problem:
, in which case it was said to the reporter "the server is buggy, go
tell to the producer". Now, before trying, probably in vain, to talk
with some Apple guy, I'd like to know the opinion of someone slightly
more expert than me (I have used smb/cifs 5-6 times in all my life),
also because my "conjecture" doesn't explain everything... in
particular it's a mistery for me the fact that one of the two sites I
linked in the former email claimed to have mounted successfully a Time
Capsule with a share name containing whitespaces. I'll try to contact
the writer of that page (notice that before trying changing the share name, I had
tried changing the Time Capsule firmware, installing all the 3 available
versions with no luck, so the difference isn't there).
In the meanwhile, any hint? I anyone connecting to a Time Capsule without
