Restarting a saved image with the browser loaded

I saved my image using Visual GST then tried to reload it from the command line like this:

gst-browser -I eli.im

The prompt displays nothing - I get an icon in the dock telling me that an application has launched but no other reaction. Then if I hit Control-C, it displays this the stack trace shown at the bottom of this message. Should this work? Am I reloading the image incorrectly?

The attached patch seems to do it, but I'd like confirmation from Gwen
that (1) it is correct; (2) it does not leak memory.

Now I'm nearly at the point where I can start bothering the poor VisualGST developers instead of you! :)

Good.  So the second time you're running "gst -I eli.im" or still
"gst-browser -I eli.im"?

Your init.st is doing the same thing that using gst-browser would do.

Oops. You're right - if I remove the init.st and use gst-browser, it works then as well. Not sure how I ended up thinking that init.st was necessary.

Probably because "gst -I eli.im" does not bring up a REPL.  It starts
the Gtk message loop.  If you saw the REPL, probably you would have
tried gst-browser the second time as well.
