Re: NSDocument with NSMatrix crasher (10.4)

Matt,

Thanks for trying this out.

One small variation:

If you enter text into the first cell of the matrix (cell at row 0, 
column 0) the app doesn't crash.  Try entering text into a cell other 
than that one and see if you are able to reproduce.  In addition (as 
per the instructions) it's specific to documents that have been 
opened.  New documents work just fine.

I just ran through this with a friend of mine and the same thing 
happened for him so it's not specific to my machine / environment.

Here's a more formal crash report:
