[Virtual-pkg-base-maintainers] Bug#840557: base: Shutdown button doesn't work the first time it is clicked

[Tama]

Package: base
Severity: normal

Dear Maintainer,

When I open the menu in the top-right and then click the icon for shutting down, it usually doesn't work the first time I do this, but it works fine the second time. That means I have to click 4 times each time I want to shutdown, instead of twice. Running `sudo shutdown -h now` from the terminal works immediately every time.
