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.

Ikumi Keita
