Comment 6 for bug 420546

I believe the reporter of this issue has the environment variable

export G_DEBUG=fatal_warnings

set. However, what is happening is that gnome-mplayer is shutting down and trying to gracefully shutdown the threadpool for retrieving metadata. But gtk is not handling a empty/flushed pool correctly and issuing the error.

I put in a workaround to not call this function when running under the control of gecko-mediaplayer
