Summary:  NSBrowser releases matrix when it should not

Original Submission:  In NSBrowser.m around line 2714 RELEASE(matrix) is 
causing probles. Browser tries to use that matrix later, but it is released. I 
have tried to trace this bug, but i had no time. What i have found is, that it 
is sometimes trying to send messages to deallocated matrix when using more 
column browser and active delegate. Removing that RELEASE solves the problem.

I am not able to surely reproduce this bug.

AUTORELEASE instead of RELEASE seems to work too (no crashes so far).

The problem is probably not in this RELEASE, because in the line preceeding it 
the matrix is retained by bc:
  [bc setColumnMatrix: matrix]
Can you produce a stack trace, please?
