Doh! You're dead right of course.

I guess that means reinstalling all packages. There doesn't seem to be a
way to figure out where (in the filesystem tree) the problem is.

As I understand it (I'm open to correction), this doesn't necessarily
indicate a bad disk. A crash or reset could apparently cause this
inconsistency -- at the point of reset one disk having been written and the
other about to be. This certainly hasn't happened often, but possibly once
or twice.
I'm running a long smart test of both disks now to see does that turn
anything up.
