Strange 404 errors with bits of jQuery library code

I've got a script that emails me when I get 404 errors on my site. In the past few months, I've seen lots of errors coming back that have various bits of the jQuery library in the URL. I'm wondering if anyone else has seen this sort of thing and what they did to fix it.

The 404 errors appear to come from a wide variety of browsers and platforms. (Windows + IE 8, Mac + Safari, etc.)

Examples:
