I think this crash related to this crash https://github.com/bluelinelabs/Conductor/issues/515 I tried to reproduce this crash like said @chichkanov but I can't repoduce it. I was able to reproduce it manuаlly with postDelay. In my architecture I have master controller and in master controller I have child controller and bottom navigation. I added code to one of my controller which push controller after 5 second. But before this push happens I switch to another tab in bottom navigation with setRoot and then after few second code in postDelay trigger and this crash happens.

I also tried to run monkey test for my application and wanted to reproduce the crashes that I declared here, but I could not reproduce any of them.

This should be fixed in the 3.0.0 release. Please feel free to reopen if you still have the issue after updating!

This crash did not occur in version 3.0 stable. But for the latest SNAPSHOT version it happens again. In latest version of my app I enabled minification and obfuscation code.
