No, I can't prove it, and I'm not even sure that _only_ updates could 
trigger update-grub - but I _am_ certain it would be an update, not an 
actual "install".  Is that a terribly important difference?  Probably not...

Absolutely - whatever your underlying problem, and the mechanics that 
trigger it, I have no doubt there's something wrong in the update-grub 
process.  All I can say with certainty is that I don't have a problem 
anymore.
