Thanks, that is a nice workaround!
However I believe this is a bug in articulate.ly.

Also in my example the trill spanner is meant to stop before the rest: 
it is *not* a trill on a rest.
Use of \startTrillSpan and \stopTrillSpan is described in [1].
E.g. the following code means that the trill begins on c and ends at the 
end of f, i.e. before g:

c4 \startTrillSpan d e f
g4 \stopTrillSpan a b c'

and indeed it does, both visually and (if you use \articulate) in MIDI.
If I understand correctly, it should be interpreted as "start the trill 
when c4 starts and stop the trill when g4 starts".

I would expect \articulate to correctly handle trill spanners regardless 
to what \stopTrillSpan is attached to.

Best wishes.
Davide
