Select device from different location crash

[Jamie D]

Hmm, I think I know why the second crash is happening. It's not the keypress but when it reached some devices it crashes. I have multiple locations in my account, if I select a device from a different location (any device) it crashes with this trace )this one happened when I used a mouse to select a device in a non default location:

Unhandled exception. System.NullReferenceException: Object reference not set to an instance of an object.
