Coding system problem.

Hi, I have a problem with XEmacs MULE which I need to get fixed for the next preview-latex release (and it will occur with AUCTeX as well unless I am mistaken). Debugger entered--Lisp error: (error "No such coding system" iso-latin-1-unix) set-process-coding-system(#<process "Preview-LaTeX" pid 8613 state:run> iso-latin-1-unix) byte-code("..."

The coding system actually is _verbatim_ gotten from buffer-file-coding-system where it has been automatically set by XEmacs, so XEmacs should have heard of it, shouldn't it? Any ideas what I might be doing wrong? This is XEmacs 21.4.17, RedHat build. Is this expected behavior? -- David Kastrup, Kriemhildstr. 15, 44793 Bochum
