Steps to reproduce the problem:
Run some app-- say the k-9 material app-- in ChromeOS on a Samsung Chromebook Pro and view any email.

What is the expected behavior?
You should see the email content displayed.

What went wrong?
The app disappears-- without a crash message on screen.  The following appears in logcat:

E ConsumerBase:  [Almost done...] getOccupancyHistory:  ConsumerBase is abandoned!
E Layer: [Almost done...] failed to obtain occupancy history (-19)
WindowManager:  WIN DEATH: Window{etcetcetc}

Did this work before? Yes About two ChromeOS dev updates ago-- don't know the name of that release.

Chrome version: 61.0.3163.47  Channel: dev
OS Version: 61.0.3163.47 (Official Build) dev (64-bit)
Flash Version: 26.0.0.137

The error does not appear with all apps, but it does with some apps and is easily reproducible.  This is definitely a regression as the affected apps were working about two weeks ago.

Not sure if this bug is connected to  bug #739296  but it looks like a similar error.
