If this happens, than it is a bug. Could you provide code and 
instructions to reproduce it?
I did inspect the NSBrowser code to find a possible cause for this, but 
most the calls to [tableView:objectValueForTableColumn:row:] seem to be 
protected by explicit checks or a call to rowAtPoint:. This would leave
drawRow:clipRect: as a potential problem, but here we have this check in 
the calling drawRect:. No idea how this still could go wrong.
