Error on running gadget locally

[dwlovell]

I have installed Eclipse and OSDE using the instructions provided.
When I run the gadget locally, it does render, however in all browsers
I see a script error:

Line: 1520
Error: 'path' is null or not an object

Is something not configured correctly? I see this on a default empty
gadget that has not yet been modified. If I click through the script
error, I can see rendering, but subsequent calls to the opensocial api
are failing and I cannot determine yet if the first failure is
breaking the rest of the script, etc.

Any ideas? I didn't see this listed as a defect on the issues list, so
I figured it is probably something on my end.
