It will always store data of adjacent polygons in a "redundant" way. ESRI ArcGIS uses the same model. If you are looking for a topological file format, you could use GRASS and use the GRASS digitizing tools (outside or within QGIS). I am bit surprised that the "topological editing" of QGIS doesn't work in your installation. It works fine with my data. Can you post a bit more information about your installation, such as QGIS version, operating system, etc.?
