I've now rebuilt and tested with the default options (i.e. including
dbus), and I'm still not seeing the specific error you mentioned.  I am
however getting crashes (with different-looking backtraces), so there
are clearly several problems to be fixed before this package is ready
for prime time.

This turns out to be a side-effect of building vlc without lua support,
because it uses lua for its extension modules.  I'm trying out a
version of the package with lua enabled and we'll see how much that

You had, of course, already done this.  Thank you, and sorry for the
confusion.  For my information, since it looks like I'm going to have
to do a bunch of testing to at least put together a reasonable error
report, how did you do this?  Option debug to vlc and adding -g to
CFLAGS, or is there a pkgsrc switch for this that I've forgotten about?

Thanks for being so quick to test.
