**The only thing I can think of that has canon support about why Hermione 
is raving that Harry might be expelled is because of last year during 
the graveyard scene. It's apparent that students of Hogwarts are only 
allowed to do magic AT Hogwarts.**

Actually, we don't know this for sure. As harry's never gone away for a school break we don't know if they have the same letter handout for Christmas or Easter break. 

And we do know from PoA and GoF that they can do magic in Hogsmeade - Hermione moves the tree, for example, without concern for doing magic away from school. 

It's a possible explanation, though, as Harry's in the Muggle world while at the graveyard, and that might be enough to tip the scale against him.
