Javascript error with upfront (last version) when i insert map


I have a javascript error when I insert a map area with spirit + upftont theme :
"Unexpected token u" /// found in line 1.
And this message : "This is where the map comes in." in the place of map area.

I can see the map with upfront enabled ... but this error appear when I disable upftont édition.

It seems to be a bug ... Infos / I have your google map plugin installed.

Thank you for your help ...
