Thanks, Patrick. Between that bug and all the others that have been
marked as a duplicate of it I think it's safe to say that it is the same
issue.

I thought it seemed somewhat familiar and I now am reasonably sure that
I have seen and researched it before but had forgotten the outcome.
Turning off Caret Mode works for me, as observed in
http://bugzilla.gnome.org/show_bug.cgi?id=318973#c9. Having forgotten
that I've most likely either enabled Caret Mode inadvertently, or the
cat did it and I failed to notice.

Thanks again for the pointer.
