Ok. This is just the "final" symptom, however, things start going wrong
much earlier (and earlier indeed, than I have realized, previously), at:

Trace:
/data/home/anders/Coding/rkward-0.7.4/rkward/rbackend/rktransmitter.cpp
- function disconnected line 266

(line number is different in the appimage, but same issue).

It seems like the local socket that the frontend and backend process
use for communication does not work. I suspect that may be some
permission problem, here.

Unfortunately, the debug code that is supposed to provide some details
on this does not appear to write to rkward.frontend. I suspect it gets
written to stderr, instead. Could you run as:

  rkward --debug-level 4 --debug-output terminal 2> output.log

and post output.log (the relevant lines will be around the search string
"--server-name"), which should show, where creating the socket is
attempted?

Probably something form QWebEngine. I'm not sure whether this is
something to worry about, but definitely looks like an unrelated
problem.

That could play a role, but again, I suspect a permission problem.
