NSComboBoxCell bug

[Andreas Höschler]

Hello all,

I have just discovered a bug in NSComboBoxCell. Popping up the combo 
box and selecting an item leads to the following stack trace (when 
setCompletes: is set to yes):

#0  -[NSComboBoxCell completedString:] (self=0x8956bd0, _cmd=0xfee93360,
substring=0x925f4e0) at NSComboBoxCell.m:1383
#1  0xfeccfbcc in -[NSComboBoxCell textDidChange:] (self=0x8956bd0,
_cmd=0xfee93310, notification=0xfee93360)
    at NSComboBoxCell.m:1827

completedString: should not be called when the user selects an item 
from the combo table view. It should only be called when the user 
enters text. Where do we fix that? I am sure I could find a hook 
somewhere, but if anyone knows this code better and finds the right 
line earlier...

Thanks,

 Andreas
