Errors on console when unlocking screen

[Ross Burton]

If you run gnome-screensaver in a terminal, when the screen locks/unlocks (I
can't tell, obviously) this error is printed:

(gnome-screensaver:3799): GLib-GObject-CRITICAL **: g_value_get_flags: assertion
`G_VALUE_HOLDS_FLAGS (value)' failed

[Oliver Grawert (ogra)]

hmm, i neither get that in .xsession-errors nor if i run gnome-screensaver from
console...

I got a stack trace from gdb, though it's not totally useful as I'm missing
symbols in gnome-screensaver:

Forgot to mention this happens when it is about to blank the screen.

I'm going to upload 0.0.15 - could you test with this one?

Can't replicate in latest release, closing.
