Same query sent twice clears the Grid / QueryReadStore

Description
When using a Grid with queryReadStore and sending a new query via
var model = dijit.byId("grid").model
model.query = {testAttribute:dojo.byId("queryValue").value};
model.refresh(); // Updates model data with store data.
it is supposed to fill the Grid with new data - which it does normally. If you resend the same query though (if "testAttribute" has the same value as sent before), it somehow clears the Grid and no further query succeeds in filling it with data again.
