You have to define maxResolution for the overviewMap! 
Try it with the code of my example:

Define a option variable for the overviewmap. For maxResolution you need the 
horizontal extent of your bounds (here 17003.71). If your ovmap like a lens 
you have to turn this value.

  var ovmapOptions31467 = {
     maxResolution: 17003.71/256,

Then add the mapOptions parameter when you call the OverviewMap constructor:
  map_31467.addControl(new OpenLayers.Control.OverviewMap(
     {mapOptions: ovmapOptions31467}));

This should be the solution of your problem.
