Menu actions don't work after changing password

After changing my password via the user accounts plug (without unlocking it with admin rights), none of the logout/shutdown/restart actions work anymore.

I get the dialog box asking me to confirm, but confirming does nothing. Following error printed in wingpanel's terminal output

```
GDBus.Error:org.freedesktop.login1.NoUserForPID: Caller does not belong to any logged in user or lingering user
```
