I'm trying to see if I can replicate the Google map display.
Can you confirm that the issue with the jquery-1.10.2.min.map file is only happening in Chrome?
JS map files are a relatively new Chrome debugging aid, which have nothing to do with Google maps. The .map files allow developers to "map" a compressed JS file on to a non-compresed one, so they can debug production sites without having to fully enable debug mode on the server side and load everything uncompressed. It's kind of "debugging on demand" for minified JS.
So if you are debugging a site in production mode, so all the scripts are minified, and an error gets tossed, if the JS file tossing the error says it has a map (which jQuery does) Chrome's JS debugger will automatically attempt to load it, and show you the full file in the debugger.
Long story short, J! will need to start shipping the .map for jQuery.
Note that I *think* this should only effect people who have used Chrome's dev tools on a given site, so your users probably won't see it.
If it bugs you, you can of course just upload the missing .map file, from jQuery's site, to the specified location. Or you can turn off the .map feature in Chrome's dev tools.
