TypeError: Cannot read property 'map' of undefined

Something goes wrong when I click the "Show Keybase" tab on Ubuntu 16.04.
A wrongly displayed window appears at far right (too far) of my screen.
I'm still able to read that I should execute the "keybase log send" command.
What I successfully did.

The window shows also this error details:
"

That's all I know.

Reproduce the failure by opening the "Show Keybase" tab on Ubuntu 16.04, then inspect the reported stack in /opt/keybase/resources/app/desktop/dist/component-loader.bundle.js. Use the provided log id if diagnostics are needed; done means the window is positioned correctly and the tab no longer shows the TypeError.
