Thanks for the report. This is a known problem, one which I actually
thought I'd already fixed! But apparently I wavered on whether the
TEXT-appending "convenience" was actually a convenience or not, and then
got distracted.

Thanks for "new" and "old", I missed those somehow. I was thinking I'd
just check for "not" and "or" explicitly. Anyway, I'll get this fixed
later today.

This is another known problem, one that is requiring some coordination
with Andy Cohen on the nnselect backend (it's actually nnselect that is
swallowing the errors). This will get fixed before too long.

Thanks,
Eric
