Let's wait until M-56 has had a bit of time to bake in stable channel before doing this.

Hi, on ChromeOS, the Bluetooth settings UI doesn't work correctly. If click toggle button to turn on Bluetooth or click the settings button, the NOTREACHED() is called and causes crash:
https://cs.chromium.org/chromium/src/ash/common/system/chromeos/bluetooth/tray_bluetooth.cc?l=458

Re-opening this bug. fukino@, can you check to see if your recent cleanup could have been responsible for the crash mentioned in #6?

juncai@, can you clarify which device, channel, and chrome version you are using?

I'll look into this.

Fix the crash on clicking buttons in Bluetooth system menu in debug build.

In https://codereview.chromium.org/2684293002, 'else' before NOTREACHED() was
accidentally dropped. It caused the crash on debug build.

Hi, tdanderson@, sorry that I didn't see the comment earlier. I just built Chrome from master branch and ran it and saw the crash.

Thanks juncai@ for the report. It's fixed on ToT.

No problem. Thanks fukino@ for the fix.
