The steps I used to reproduce this are given below:
1) Run emacs-w32 -Q & in bash
2) M-x toggle-debug-on-error to enable the Emacs Lisp Debugger
3) C-x d to open a directory in Dired
4) Specify a remote directory
5) After the Dired buffer loads, open a file in the remote directory 
with <RET>
6) Minimize the Emacs window and wait

I'm not sure whether it's necessary to open the file to reproduce this 
error. I'll test this next.


Cheers,

SDS
