The reason I filed this bug is that many times there is no way to stop
the blinking, e.g. when doing an update via update-manager. What seems
to happen is that both a window and its MODAL child window start
blinking, and there is no way to stop the blinking of the parent.

While might be a bug in the apps, this happens for many apps (e.g. xmms)
and therefore I though a workaround was needed at the libwnck level.
