[Message part 1 (text/plain, inline)]
Hello,
In my TeX-command-list, I have things like this:
("View with okular" "okular %s.pdf" TeX-run-silent nil nil)
This command works but displays an error message in the Emacs echo area
after okular has been started ("Wrong type argument: stringp, nil").
This is because TeX-run-silent does:
(if TeX-after-start-process-function
(funcall TeX-after-start-process-function process))
which, in my case, calls TeX-adjust-process-coding-system which runs:
(let ((cs (coding-system-base (with-current-buffer TeX-command-buffer
buffer-file-coding-system))))
However, in the context described here, TeX-command-buffer is nil at
this point, hence the aforementioned error that aborts
TeX-adjust-process-coding-system. With the attached patch,
TeX-adjust-process-coding-system completes normally.
Can someone have a look and apply the patch, or otherwise fix the
problem if there is a better way?
Thanks & regards
P.S. : all this with the current state of 'master', namely at commit
06226ea5e95de16250c18ec3fd033f96237fa642 of the AUCTeX Git
repository.

Thanks for the report. I suppose that the problem occurs only when you
issue the command "View with okular" before excecuting any tex commands
within AUCTeX, doesn't it?
Anyway, there is similar problem with typing "C-c C-c Queue RET".
Considering that many codes in AUCTeX assumes that `TeX-command-buffer'
has suitable value, it seems better to make it sure that
`TeX-command-buffer' is set every time. Cound you test the patch listed
below? If it fixes your problem, I'll install in the git repository.
I know this patch introduces a small overhead, but I expect that's
negligibly tiny.
Regards,
Ikumi Keita

Correct: if I run the LaTeX "TeX command" before, no error message.
