Hi Peter,

Thanks for your report.

This is from the "draft mode" introduced by Nicolas recently.

Perhaps to get your work done for now you can try to change
org-export-with-broken-links, though I doubt it will work in this
particular case.

Nicolas will fix this when he’s back, I’m sure.  I haven’t studied the
"barf code" and I will therefore not attempt to fix it.

Rasmus
