Actually I think Matt G. is on the right track, but not exactly. Delete
your preferences for Interface Builder; or locate the key where IB is
storing the state for your NSTableView columns. I encountered this same
after removing or renaming some columns from a TableView. However,
InterfaceBuilder has already cached the names and states of the
columns. Well those columns don't exist any more... IB panics and can't
open the nib file without whacking some columns for you. Not a pleasant
experience.

Easy solution:
defaults delete com.apple.InterfaceBuilder

More accurate solution:
defaults read com.apple.InterfaceBuilder | more
then look for the key with the autosave-name of your table, e.g.
"NSTableView Columns MLSlacker2OutlineView"

then do
defaults delete com.apple.InterfaceBuilder "the key name"
e.g.
defaults delete com.apple.InterfaceBuilder "NSTableView Columns
MLSlacker2OutlineView"

This seems like a major bug in IB, to me, but I don't follow the
ProjectBuilder mailing list. Can anyone confirm it's been reported to
apple?
