It appears that the Javascript minimization of the Resource Loader works incorrectly for Javascript from the OpenLayers application (which is used by the Semantic Maps extension). See here:

The Javascript error seems to come from the fact that the value "8.58306884765625E-5" gets turned into:

8.58306884765625E
-5

...and the major browsers don't understand that. I'm guessing that the minimizer considers "-" to be a safe character to put a newline before, but that's not the case here.

By the way, as you might expect, with debugging on, the JS works fine:
