[Ben Klaasen <1492764@xxxxxxxxxxxxxxxxxx>]

This happens to me running 64-bit Xubuntu 15.10 on a Dell Latitude
E7440, when unlocking the screen after it's been sent to sleep. Light
Locker Settings claims "Your screensaver settings are managed by Xfce
Power Manager [Open]"; opening that utility, it's not clear what I need
to switch off to hand control back to Light Locker without losing other
power management options. This might all be beside the point.

In any case, I'm tailing /var/log/syslog all the time; when I return to
my machine after the screen has been switched off for a time, after
presenting my credentials to unlock the running session, I'm presented
with an apport dialog stating that I'm attempting a task that requires
root privileges (I'm paraphrasing, I'll update with the full details
later.)

/var/log/syslog contains the following stack trace:
