Miro produces crash message when attempting to enter fullscreen

[Brian Rogers]

If while playing a video, I attempt to go into full-screen mode by double-clicking the video area or by clicking on the fullscreen button, Miro just pops up a "Miro has crashed" window. Aside from the error report, Miro keeps functioning normally, but does not enter fullscreen mode.

From then on, it ignores any attempt to switch to fullscreen, without generating an additional error message. I've observed this behavior on two separate systems running Ubuntu 11.10, and I also observe it if I start a fresh Miro profile.

I am running Miro 4.0.3-2. I'm attaching the contents of the error message.

Status changed to 'Confirmed' because the bug affects multiple users.

Reproduced in up-to-date Arch with Gnome Shell. Problem started after updating to Miro 4.

Note that the key error in the above miro-error.txt attachment is:

 DBusException: org.freedesktop.DBus.Error.UnknownMethod: Method "Inhibit" with signature "ss" on interface "(null)" doesn't exist

I get that same error when running the code at http://rschroll.github.io/code/disablescreensaver.py
which is designed to disable screensavers.
