[Bug 79445] Re: rhythmbox error report "Unknown playback error" needs improvement

[Sebastien Bacher]

Upstream comment:

"I'm not entirely certain that "Failed to sync gstreamer pipeline in open
operation" or "Failed to set gstreamer element state" is any more enlightening
than "Unknown playback error" for most people. It would also mean that
translators have to translate those too."
