No. The ListStore is data associated with that particular row of the
TreeStore, and will be displayed in a different TreeView when

There is no attempt to display the column.

I am not trying to display it, but it's still not working. The error
specifically occurs when I try and access the data, which suggests to me
that something's not where I think it should be.
