[Zope] Transience errors in 2.7.2?

I'm getting the following on a Zope 2.7.2 server: Module Products.Transience.Transience, line 765, in new_or_existing Module Products.Transience.Transience, line 476, in get Module Products.Transience.Transience, line 280, in _move_item Module Products.Transience.Transience, line 694, in _gc KeyError: 1109697840 I thought all these errors were fixed? (or were they finally nailed in a version later than 2.7.2?) cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk
