The problem is that not just the tex file doesn't exist but the
containing directory ~/test/ doesn't exist either.  But that seems to be
already set as `default-directory' so the shell commands testing for the
availability of the evince-based viewers should run in a non-existend
CWD.

Well, those tests will work the same no matter which
`default-directory', so we could bind `default-directory' to "~" for
those calls, I think.

I'll come to that when I find some spare time.

Bye,
