I'm sorry, I ment to get back to you, but unfortunatley this is one of
the errors that only happen occasionally. I tried a couple of scenarios,
like with and without networking, but could not reliably reproduce the
error. It does still happen from time to time.
Now, I followd your advice and produced a somewhat more informative
backtrace. How do I get rid of the ellipses? (print-length is nil)
