#398 sort not working in price editor

[Al_]

The price editor (in my German version: 'Preiseditor') appears to allow sorting by any column, i.e., investment, currency, date, price, source (?, in German 'Quelle'). Sorting by first column works. An attempt to sort by second column (currency) or by last column (source) result in sorted by first column (investment).
My environment: Ubuntu 9.10 gnome (NOT KDE), KMyMoney 1.0.2.
