tramp (2.1.7); 2.1.7 - revert-buffer gives "tramp-flush-file-property: Wrong type argument: stringp, nil"

[Jonathan Hankins]

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--


[Also tried this by starting emacs with "emacs --no-site-file -nw -q" and then
did a "load-library tramp".]  There is only 2.1.7 in my load path.  If I open
a file through tramp, for example "C-x C-f /sudo::/root/tempfile", modify it
(not sure if this matters) then do a "revert-buffer" I get the error
"tramp-flush-file-property: Wrong type argument: stringp, nil".  This is also
triggered during VC operations when it tried to revert a buffer.
