tramp (2.0.50); Spurious buffer opens when saving on a FAT system

[Torsten Bronger]

Enter your bug report in this message, including as much detail as you
possibly can about the problem, what you did to cause it and what the
local and remote machines are.

If you can give a simple set of instructions to make this bug happen
reliably, please include those.  Thank you for helping kill bugs in
TRAMP.

Another useful thing to do is to put (setq tramp-debug-buffer t) in
the ~/.emacs file and to repeat the bug.  Then, include the contents
of the *tramp/foo* buffer and the *debug tramp/foo* buffer in your bug
report.

--bug report follows this line--

I use Tramp for editing a remote file trhough a ssh connection.  The file is on
a FAT32 filesystem.  When I write the file for the first time in the Emacs
session, a buffer named *trams/ssh bob* opens with the following contents:

(nil 1 0 100 (17216 3044) (17216 3045) (17216 3045) 461 33279 t (3 . 52893) -1)

*Messages* contains:

I suspect it has something to do with the fact that the bakup file could not be
saved.  Saving the file works but this behaviour is slightly annoying.  Can it
be avoided?
