Thanks for your quick reply. You sessionInfo() output gave me the hint 
that I did not update some of the annotation packages whose existence I 
wasn't  aware of (initially, I updated only the mouse4302 package) :) 
After updating the rest, all seems to work again.

However, from an user's point of view, I would rather like to see an 
appropriate error message coming up which complains about non-matching 
versions of the required package. Is there such a mechanism in 
Bioconductor/R?

Ciao,
Sebastian
