System info

App version: 2.0.0-RC5 (Where did you download the app?)

Android version: all? (Please mention if you are using a custom rom!)

Bug description

Steps to reproduce:
Not really reproducible. Going back from player to queue. According to Google Play, this is the most-experienced crash in 2.0.0. I thought that this is caused by switching themes but having this occur during normal use is a pretty big problem. One (apparently failed) attempt to fix this can be found in #4242.

First occurred: at least RC5

Environment: (Settings you have changed (e.g. Auto Download). "Unusual" devices you use (e.g. Bluetooth headphones). Did you select another media player?)
