As many asset pipelines concatenate JavaScript files and then use minifiers on the final result, this breaks asset pipelines that use Yuglify. Django-pipeline is one such case that uses Yuglify by default.

Yuglify is installable through npm.

I just verified that yuflify parses 1.10 no problem.

$ rm -rf bower_components && bower cache clean && bower install jquery#~1.10
bower deleted       Cached package jquery: /home/jon/.cache/bower/packages/fe2fe255e91d251051d543998aa8327a/1.10.2

Given that every jQuery build is validated with JSHint and tested successfully in many browsers, this is almost certainly a yuglify issue. But please come back here if you identify a specific line or expression we should look at.
