I'm not seeing these errors in Chrome, but Firefox displays them no matter what I seem to click on. I believe the URL needs to be fixed for the Resource URL (notice the 2 forward slashes):
Source map error: request failed with status 404
Resource URL: https://trunk-mysql.nightly.sakaiproject.org/library/webjars*//*qtip2/3.0.3/jquery.qtip.min.js?version=03210035
Source Map URL: jquery.qtip.min.map
I do not see these errors in 19.
