Description:
The ListView that a user drags columns to when creating an index is broken. Instead of receiving details of columns, it receives NULL values.

How to repeat:
Go to the Catalogs section.
Go to a table.
Add a new index.
Drag a column into the ListView to add it to the index.
Note that nothing appears to happen.
Try dragging another column into the ListView.
Note again that nothing appears to happen.
Click around inside the ListView.
Note that there *ARE* rows being appended to the ListStore, but these rows all have NULL values in them instead of the column's details.
Hit the apply button to submit the changes.
Note the SQL generated. Instead of listing the names of the columns that were dragged, index definition instead has a list of NULL values, eg:

ADD INDEX `IDX_Line` ( `(null)`, `(null)`, `(null)` );

Note that the ListStore *is* populated correctly for existing indexes - this error is in the drag & drop functionality when adding columns to an index.

Suggested fix:
Fix drag & drop of columns into the ListStore.
