I use Lancelot as application launcher, in a system
where there are multiple users time-sharing the
same terminal. I have seen the following:

The list of users in the "switch user" menu is set
the first time this menu is opened. After that, if
users log in or out, the list does not show them.

What I expect: The list of users shown should always
reflect the actual sessions at the time it is opened.

I've found no similar bug reported upstream, so this
may or may not be Debian-specific.

Thanks for your good work,
       Shai.
