Hi,
I've an app with tab bars + ion-list (ng-repeats) and when i use the "pull to refresh" feature, everything is displaying fine but i got an error on the ionic serve console
As i never use iosolateScope and i only see error logs related to ionic.bundle i don’t know how to debug this 
So : how to debug ?
And : what is the problem here ? (i’m using last stable build of ionic
**Error: tabNavElement.isolateScope(...) is undefined**
