Android ClassNotFoundException to support v7 TestActivity

I have an application for which I just received a crash report. I don't have complete stack traces with me right now, but that was from ActivityLoader.performLaunchActivity.

The class he is trying to run is android.support.v7.widget.TestActivity. Of course, I never try to download this activity anywhere in my application.

The device is Samsung’s Galaxy Nexus 4.1.1, based on the root. Glass wool looked normal to me (there was nothing, or something like that).

Has anyone ever seen anything like this?

EDIT: Here's a stacktrace
