Google Map Custom Lens Template Render Issue

[eroby]

Am using Plone 4.1 and Daviz version 7.4. The following is a part of the custom lens template that is failing:

<a style="text-decoration:none" ex:href-content=".record" 
  target="newWin" 
   title="Click to view full details">
  <img height="100px" width="100px" style="padding:5px" ex:src-content=".thumbnail" />
</a>

An example of a definition for .thumbnail is -

http://maps.google.com/maps/api/staticmap?center=48.148376300000002,-122.4197436&zoom=2&size=100x100&markers=color:orange%7Clabel:%7C48.148376300000002,-122.4197436&maptype=satellite&sensor=false

When I inspect this element with FireFox Web Tools and 'Copy Outer HTML' it shows the following -

http://maps.google.com/maps/api/staticmap?center=48.148376300000002,-122.4197436&zoom=2&size=100x100&markers=color:orange%7Clabel:%7C48.148376300000002,-122.4197436&maptype=satellite&sensor=false

Which results in a 404 @ Google and no thumbnail.

I use the same lens template detail in an accompanying Timeline and Table view and they render as expected. Also - I ONLY experienced this bug when I updated to 7.4 from 6.0.

Thanks in advance...
