You don't get to this point, so it's not the problem you have now, but I assume your real code invokes [super initWithFrame:...]?

First step: Break in -awakeFromNib and verify that browser is not nil.
Second step: Maybe an NSBrowser doesn't instantiate any matrices until you have responded to browser:numberOfRowsInColumn: with a non-zero value?
