Moving a mouse on Glass Home causes it to crash

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Plug in a mouse via OTG cable, or pair via Bluetooth with an appropriate 
configuration
2. Open Glass Home
3. Move the mouse

What is the expected output? What do you see instead?
I would expect the mouse cursor to move and nothing else to happen.
Instead, the cursor moves and Glass Home promptly crashes.

What version of the product are you using? On what operating system?
Confirmed in both XE11 and XE12, second-generation Glass.

Please provide any additional information below.
The attached mouse works in adb-installed standard Android applications as 
expected. I have tried both a USB mouse and a Bluetooth keyboard/mouse 
combination device.

This doesn't exactly seem like an issue with the Mirror API or the GDK, so I 
don't believe that it should be here. I'm not sure, though.

Hello,

Sorry for the late reply regarding this... This is not really related to the 
GDK but still part of the platform.
Unfortunately, it's not easy for us to reproduce and we would need your help to 
investigate: could you look at the log and check if there's a stack trace you 
could share with us?

You can use wireless adb to run logcat while the mouse is plugged-in:

I don't have my OTG cable handy at the moment, so here's a traceback I grabbed 
from a bluetooth mouse, looks like Home is trying to pass generic mouse input 
through the touchpad gesture detector:
