Code review comment for lp:~darkxst/unity-settings-daemon/lp1377847

Using this version I just had a segfault in gsd_idle_monitor_handle_xevent_all()

since the ppa doesn't have ddebs I can get a debug backtrace, but it segfaults in a call to g_hash_table_contains

what I did
- using unity, lock the screen manually
- walk away from the computer for half an hour
- come back and move the mouse to get the lock screen/unlock

It doesn't seem to happen every time with those steps though (or the time without touching the computer matters, I tried just waiting for the screen to dim/turn off when I did testing)
