JavaScript Error on "Shout from a Favorite Place..." when using "Shout & Message"

JavaScript Error on "Shout from a Favorite Place..." when using "Shout & Message":

I noticed that when I try to shout & message from a favorite place that "nothing happens" when I click on "Shout & Message". Firebug shows the following error:

showShoutMessageFieldList is not defined

I am using FireFox 3 on OS X. I have seen this happen several times, even after a browser restart. As of now I'm unable to message--I can only shout my location with no message. Sad!
