Miro Won't Launch

[Larry]

When I try to launch Miro from the Slingshot, nothing happens. When I launch it from the terminal, I get this response:

tim@tim-All-Series:~$ miro

Please report this issue to the developers of Miro.

Affects me too. According to http://lists.opensuse.org/opensuse/2013-04/msg01103.html it's due to transition from GStreamer 0.10 to 1.0, so marking confirmed for Ubuntu's Miro package.

bug #1357800 seems to be used to track this issue, but it's set to private.
