Steps to reproduce:
1) navigate from MainFragment to FirstFragment
2) navigate to SecondFragment

The SecondFragment pops back to the FirstFragment in its onViewCreated method. Then back in the FirstFragment, we pop off the FirstFragment and navigate to the ThirdFragment, this is where app crashes.

This worked perfectly fine with 2.5.3.

Can you pls have a look since this prevents updating to a version newer than 2.5.3?
