If I install an app that was not present at connection time, and then manually open it, the following stack is logged in the Browser Console:

TypeError: a is null: WebappsStore.prototype._onAppOpen@resource://gre/modules/commonjs/toolkit/loader.js -> file:///Users/jryans/projects/mozilla/gecko/browser/devtools//app-manager/webapps-store.js:201

Ryan, how did you install the app? (I can't reproduce here)

I can't reproduce if I install the app from the marketplace.

Hmm, I can't reproduce either anymore.  Will update with better STR if it happens again.
