Git commit ad3973c82159befd92d2db199058f12e4cabb911 by David Edmundson. Committed on 03/03/2012 at 13:16. Pushed by davidedmundson into branch 'master'. Convert columns to a QHash rather than a QVector in ExtraModelProxy Previously number of columns was allocated to be the same as the number of rows which makes no sense which caused a crash when the source model had no rows and a column was added.
