 it seems that is still true with the actual trunk r14856.

 After adding a layer it does not show in the overview window unless OTFR
 is activated. If you activate OTFR after having added the layer, then the
 overview show something but the canvas extent goes wild. In this case
 using "zoom to layer" does not help, it is needed to give a "touch" with
 the pan tool and the canvas extent return more or less normal.

 If OTFR is activated before adding the layer (and adding it to the
 overview) then the overview shows the layer but very very small...
 basically useless... and there is no way to recover the situation, even
 trying with "zoom to layer" or other tools.

 With render caching enabled the crashes when resizing the overview window
 are still confirmed... but this is another problem already described in
 another ticket.
