commit c775e5d1ae2ab4b194ee3c0f18523c603cf4d6ec

    Return true when popping from FragmentNavigator
   
    Since NavController only updates its back stack when
    a Navigator returns true from popBackStack(), ensure
    that all updates to the FragmentNavigator's back stack
    (i.e., calling removeLast()) are paired with returning
    true from popBackStack().
   
    This ensures that the FragmentManager state and the
    NavController states don't get out of sync.

    Test: tested in sample app from bug

This is actually an issue where the NavController's back stack state is going out of sync with the FragmentManager / FragmentNavigator's state. This has been fixed and will be available in the next release.

Nice job! A quick response!

I still get this error using the lastest 1.0.0 release :

    implementation 'android.arch.navigation:navigation-fragment-ktx:1.0.0'
    implementation "android.arch.navigation:navigation-ui-ktx:1.0.0"

I'm using nested graphs.

Re #7 - please file a new bug with a sample app that reproduces your issue.

Done.
