RBStoryboardPopoverSegue not working as expected on IB (on Xcode 6)

[fatuhoku]

This issue could be totally relevant or duplicate to #39 but I'd like to document it specifically anyway.

There are two view controllers: one storyboard link and one standard view controller, embedded in a navigation controller.

I created a bar button item on the navigationItem and ctrl+dragged it onto the storyboard link. I selected storyboard popover.

When run, it produces this assertion failure:

2014-10-07 18:17:16.432 MyProj[91455:1565416] *** Assertion failure in -[RBStoryboardPopoverSegue perform], /SourceCache/UIKit_Sim/UIKit-3318/UIStoryboardPopoverSegue.m:39

And the trace goes way into UIKit:

Could be related to an IB bug outlined here: http://stackoverflow.com/a/10694868/590767

But I couldn't get it to work following those instructions either.

I found out that using a STANDARD UIStoryboardPopover into a RBStoryboardLink works! The README should be updated...
