Strangeness.
When I run my application (local or deployed), the first time i load a
page (any page) on the app I get an error like the following:

A problem occurred in a Python script. Here is the sequence of

Now, when I reload the page, it works.
Once deployed, the app seems to go 'stale' for me, and i have to do
the 'reload-twice' trick to get the page to load.
This is a Wave robot, but I also have a couple of web pages i'd like
to publish on the domain as well.
thanks as always,
Christopher O'Donnell
