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-verbose 8)

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--

Hi,

I keep finding buffers that don't really need any filesystem identity,
e.g. my Gnus or Wanderlust buffers, become associated with remote tramp
paths somehow, so reading mail suddenly needs an open connection to a
remote machine.  It's very frustrating, and I can't even figure out how
to re-associate these buffers with local paths when I discover the
problem.  Can you help?

Thanks,
