Crash in _NSTableRowHeightStorage

Hi all,

I'm having a heck of a time tracking down the cause of a crash. Although the crash occurs in a number of places it always involves NSOutlineView as it computes row heights. There is also the consistent presence of _NSTableRowHeightStorage, with the crash often occurring in that object. The outline view is always connected to a delegate, and the delegate always provides the row height.

The conditions are otherwise variable. Sometimes an NSTreeController is used, sometimes an NSArrayController. Various classes are used for the nodes, some painfully simple. The catalyst for the crash also varies. It occur when code expands a node in the outline but also when the content of the outline's controller changes, as in the example below. To make matters worse, I am unable to reproduce the crash, but it occurs variably for a number of users.

I have attached a portion of one of the crash reports. Does anyone have any leads on a possible cause?
