Android App: Empty appium inspector - Failed to Dump Window Hierarchy error - disappeared in 1.4.8

On the menu page of the app I get empty Appium Inspector and “Failed to Dump Window Hierarchy” error in logs.
System: MacOS X 10.10.4
Appium: 1.4.7
App: Android. I do not know what kind of information may be helpful. Is it important that there is a DrawerLayout used in this menu?
Phone: Tried API 21 and API 19 AVM and real device with Android 5.0

Issue disappeared in 1.4.8

I’m getting this error with Appium 1.4.8 (iOS with Appium Inspector), using Genymotion and Android 4.4. This was working a while ago.
