I tested enabling and disabling addons, and it seems to be related to the Cisco AnyConnect extension.

I haven't heard of any similar crashes so this may be fixed (user was on a dev build).

@varkha can you double-check that the system menu works properly with 3rd-party VPN extensions? stevenjb@ has made some sample ones.

malcolmlorber@ can you try this out on the latest version of m-56 (beta channel) and make sure that the new 'material design' style system menu is enabled? (The ash-md flag should be set to "Default" on about:flags). If this is still reproducable can you double check about:crashes to see if a crash ID has been generated?

stevenjb@ can you provide any guidance regarding #4?

Without a crash ID it is hard to say for sure, but I suspect it may have been this:

https://crash.corp.google.com/browse?q=product.name%3D%27Chrome_ChromeOS%27%20AND%20custom_data.ChromeCrashProto.magic_signature_1.name%3D%27ash%3A%3AStatusAreaWidget%3A%3AIsNextVisibleTrayToLogout%27&ignore_case=false&enable_rewrite=true&omit_field_name=&omit_field_value=&omit_field_opt=%3D

Which has not shown up since 56.0.2924.26 (Beta channel is currently 	56.0.2924.87).

I would suggest closing this as WontFix, pending confirmation by  malcolmlorber@,

I did also try this with a third party VPN installed on ToT and it seems fine. (also I shared a VPN Demo folder in Drive with tdanderson@ and varkha@)

malcolmlorber@, friendly ping - can you still reproduce this issue on the latest dev or beta channels? If so please let us know which and indicate the chrome version you're using.

Marking as WontFix. malcolmlorber@ or anyone else, please file a new issue if you still observe this issue.
