bug#35035: 12.1.2; TeX-evince-sync-view locking up with this file

[Faheem Mitha]

Hi,

I managed to get `TeX-evince-sync-view` to consistently lock up with
this file. I realise this is a pathological case, but I still think
that it could be handled better.

I wrote a question on TeX Stack Exchange, which is currently at
https://tex.stackexchange.com/q/481892/3406

I'll mostly just reproduce that question below. The file also appears
below.

When I compile this file with AUCTeX, it shows that one page has been
compiled. When I try to view it, using `TeX-evince-sync-view`, it
shows a blank view. After I kill it, `TeX-evince-sync-view` stops
responding, and gives me a D-Bus error: "call timed out" message. I
suppose this is because the only LaTeX file here is in a different
file, and the main file doesn't have any content, but AUCTeX really
should cope better. Can anyone reproduce this?

Suggestions how to unstop D-Bus in this sort of situation (just for my
reference) would also be helpful.

Regards, Faheem Mitha
