Bug Description
When updating the details of the gnome-bugs bug tracker, which has some 13,000 watches against it, I get OOPS-1378EB433. This happens for debbugs, which has ~ 10,000 watches, too (OOPS-1378EC458).
The error raised in both cases is "ShortListTooBi

As far as we can tell, this is due to the fact that snapshot() takes a copy of all the properties of an object. In the case of a BugTracker, this includes all of its bug watches, and in the case of, say, Gnome Bugzilla, this means 13,000+ bug watches are getting copied.
This isn't something that we can fix for 3.1.12, so I'm unmilestoning and unassigining it. I'm also opening a Foundations task for it, because the Foundations team might be better placed to fix the problem than the bug team.
