Attached file testcase
Quite possible.  I'll look into this tonight.
Attached patch This could work (obsolete) — Splinter Review
This is basically the same issue as bug 307809 and has the same question -- should GetScrolledBox actually return the scrollbox for cases when the scrolled thing is not a box?
Depends on: 307809

This could work

See question in comment 4.

at least

expects the function to return a null pointer.
That's not the same GetScrolledBox.  In this bug we care about nsGrid::GetScrolledBox...

This could work

r+sr=dbaron, but please move the |deepChild| variables into the loop and remove the bogus assignment to them near the end of the loop.

This is just like bug 307809; a null-check that at least makes some sense.
