"switch user" locks screen without switching users

[SwaJime]

Binary package hint: indicator-applet-session

I cannot switch users without logging out.

Example:
   I'm logged in as "Mel"
   I left-click on the "Indicator Applet Session 0.3.7" icon.
   From the menu that pops up, I choose "John"
   The screen goes blank.
   I move the mouse, and the screen comes back requesting a password for "Mel".
   I expected it to ask for a password for John.

Ctrl-Alt-F1 through Ctrl-Alt-F12 ( or Alt-F1 through Alt-F2 ) do not switch virtual consoles.

Appears to be the same bug reported in https://bugs.launchpad.net/bugs/477474

[Kalle Valo (kvalo)]

From looking at bug #477474 looks like this is a bug in fxlrx. Maybe this bug should be marked as duplicate of that bug?

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Klaus Reichl (klaus-reichl)]

This bug is related to gdm.

Using lightdm switching users work as expected.
Using gdm, the user switch presents the screen lock window and you can switch to the user from there (which is not, what is expected).
