 The error is fixed in r56578. However showing centroids is controlled on
 3d view vector page - check load points checkbox

 Some of the default values can be set in 3d view settings.

 these things are quite experimental but the pan button should work (not
 really panning but it changes focus)

 This ticket is fixed (in terms of the initial problem).
