Package: xfce4-session
Version: 4.6.2-3
Severity: normal
After upgrading to wheezy, the suspend functionality from the logout
menu no longer works. Instead it seems I am logged out of my session and
presented with the 'slim' login screen.
In /var/log/messages I see the following line:
Feb 8 13:06:29 jberryman kernel: [70830.865667]
x-session-manag[2055]: segfault at 0 ip 0805b05d sp bf9b23d0 error 4
in xfce4-session[8048000+1c000]
I would be happy to help resolve this issue and grateful for any ideas
on work-arounds.

reopen it later.
