12314 - Assertions in table code for certain web pages

Status: VERIFIED FIXED

Description

[Scott MacGregor]

I didn't see this problem in Friday's build but I am seeing it in a tree I
pulled yesterday afternoon.

I started apprunner and went to the following url:
www.boston.com/globe/sports

I continually assert in nsCellMap::RowIsSpannedInto with the following
assertion:
NS_PRECONDITION ((0 <= aRowIndex) && (aRowIndex < mRowCount), "bad row index
arg");

Both aRowIndex and mRowCount are 0. I tried skipping past the assert and kept
hitting it. After 15 or so traps into the debugger I just killed it.

I'm going to start by assigning this to Troy as my stack trace pretty much only
has table stuff on it so I have no other place to start with.

Here is the rest of the stack:
