That doesn't look right. You probably want:

state = gst_element_get_state(...

Set an idle handler to delete the element in your main thread. You're now
deleting it in the thread context of the signal-emitting-thread, which is
not a good thing.

Mark (from Amarok) knows how to do this in KDE, it's slightly different
from glib/GNOME since KDE doesn't use GMainLoop's.
