Re: X-coding-system incompatibility, and workaround

[Tim Hesterberg]

Sorry, I should have included an example file.
Attached is an RMAIL file "bugReport".  This was created on 
GNU Emacs 22.1.1 (i386-mingw-nt5.1.2600) of 2007-06-02 on RELEASE
I have this saved in ~/mail/bugReport on my system.
I'll give some output of uuencode below, as well.

To reproduce
On another system, I start an older version of emacs using emacs -q
this version is:
GNU Emacs 21.3.1 (i386-redhat-linux-gnu, X toolkit, Xaw3d scroll bars) of 
2005-02-04 on porky.build.redhat.com
(I get the same symptoms at home, running Windows and emacs 21.3.1.)

On this system I do C-u M-x rmail
Emacs prompts for the file, and I specify ~/mail/bugReport

This results in the error message, and the following in the *Messages* buffer:
rmail-show-message: Invalid coding system: us-ascii-unix

Here's the bugReport file in uuencode format:
