Source map syntax error on jQuery upgrade - Unexpected Token : / Missing ; before statement / Expected ';'

Source map syntax error on jQuery upgrade - Unexpected Token : / Missing ; before statement / Expected ';'

I've just upgraded my C#.NET (MVC / WebAPI / Entity Framework) solution to use jQuery 2.0.3, and I'm getting a syntax error (viewable in the developer tools console) on the source map file in every browser.  In Chrome 31.0.1650.63 m, I get " Uncaught SyntaxError: Unexpected token : ".  In Firefox 26.0, I get " SyntaxError: missing ; before statement".  In all cases, the error occurs in file jquery-2.0.3.min.map.  In IE, I get "SCRIPT1004: Expected ';'  jquery-2.0.3.min.map, line 1 character 11". 

Based on the line/character note in IE, the error seems to pertain to the very first colon in the source map file - the one after 'version' in the following text:  {"version":3,"file"'...

In Chrome, on the line prior to the error, there is this message: Resource interpreted as Script but transferred with MIME type text/plain: "http://localhost/MyCerts/Scripts/jquery-2.0.3.min.map".

I tried changing my registry key for map files at Computer\HKEY_CLASSES_ROOT\.map to point to text/javascript instead of text/plain (having seen this post: http://stackoverflow.com/questions/12003107/resource-interpreted-as-script-but-transferred-with-mime-type-text-plain-for-l), but that did not fix either the error or the warning line regarding the MIME type.

Any ideas what might be causing this error / how to troubleshoot or fix?

Many thanks!
