lxsession-logout applet doesn't open

[adch99]

The lxsession-logout applet doesn't open when "logout" is clicked from the menu in lxpanel or from the task bar power button. When it is invoked from the terminal it doesn't open 60% of the time. It may be noted that this lessens to around 45% when used with the shell builtin 'time'. Pls note that these figure are purely estimations.

I have about 50 machines where this problem is occurring.

When running a gdb session (gdb lxsession-logout), the following is produced:

(gdb) run
Starting program: /usr/bin/lxsession-logout
[Thread debugging using libthread_db enabled]

*** When lxsession-logout 'hangs', the pause will be after the first "New Thread" in the debugger.
