12.04 cannot set column type

[Chris]

In 12.04, I cannot set the column type of a ListStore column.

If I create a new column, by clicking then double clicking "<define a new column>", I can type a column type and select from the list. However, on a pre-existing column there is no way for me to set the column type.
