Kids, when in doubt, go back to the basics!  :-p

I thought that I *had* run revdep-rebuild, but perhaps I am losing count with 
the different machines I look after?  Ha, ha! 

Anyway, after another irrelevant update today revdep-rebuild showed this:

Now all works as expected - apologies for the noise!
