Oh dear; thanks for this analysis.

There's a work-around, so this isn't critical enough to mandate a new
release "soon", but this definitely needs to be fixed before the next
release. I've assigned the bug to me, but I'm not sure when I'll get
time to take a look.

Matt: the config looked fairly sane, thanks. (Normally, reports like
this turn out to be configuration mistakes).
