I get the error message GET http://example.com/wp-admin/jquery-1.10.2.min.map 404 (Not Found) in the admin, and a similar message on the front-end, with the exception that the script is attempted to be loaded from /wp-includes/js/ instead.
This intermittently stops a WooCommerce extension I've been working on from doing things with javascript. My plugin does not load its own version of jQuery or anything foolish; it doesn't load or require anything beyond what WordPress and WooCommerce ships with. Sometimes my javascript will work, other times it will not. I cannot reliably reproduce unique situations that cause the two separate results.
I am using TwentyTwelve with only two plugins active - WooCommerce and my own plugin.
This problem did not occur before upgrading to 3.6.
