 It turns out this assertion failure happens in a debug build when you open
 "Page Info" even without the patches in comment:4. I'm currently trying to
 track down the cause of the assertion by binary search. But my feeling is
 that the fix for this ticket shouldn't be delayed for what appears to be
 an unrelated issue.
