Incidently I had seen the same on the same day, and asked myself the same 
question.  It did not come back later, though.

These sporadic incidents might be a problem in the session shutdown phase, 
i.e. a misunderstanding of Isabelle/ML vs. Poly/ML.  If it happens more 
frequently, I will have to look again.
