--text follows this line-- ================================================================ Dear Bug Team! This bug occurs with 21.4.22 and 21.5-b28 XEmacs 21.4 (patch 22) "Instant Classic" [Lucid] (i586-pc-win32) of Tue Jan 06 2009 on VSHELTON-PC2 XEmacs 21.5 (beta28) "fuki" [Lucid] (i586-pc-win32, Mule) of Tue Jan 06 2009 on VSHELTON-PC2 I renamed my ~/.xemacs directory to get rid of my initialization files. When I try to "ediff" two empty buffers "tmp01" and "tmp02", I get an error: C-x 2 C-x b tmp01 RET C-x o C-x b tmp02 RET C-x o M-x ediff-buffers RET RET RET => Debugger entered--Lisp error: (invalid-argument "No such coding system" emacs-internal) coding-system-property(emacs-internal pre-write-conversion) write-region("" nil "C:\\DOCUME~1\\jduthen\\LOCALS~1\\Temp/ediffceAgeH" nil silent nil excl) byte-code("..."

I could get rid of the bug and make ediff run by setting ediff-coding-system-for-write to something else than emacs-internal, for example raw-text I hope you can fix this bug.

`sendmail.el' mail client. This facility, while part of base XEmacs, is heinously underfeatured, and not going to get better in the medium term. We include it so that bug reports work without packages; we suggest that you choose and/or install one of the other mail clients from packages if you're doing something other than M-x report-xemacs-bug , or even if you are reporting bugs regularly. To choose a package from those installed, click on "Options" -> "Internet" -> "Compose Mail With ..." and decide on one from the list. Gnus and VM are full-featured and have active user communities.
