Ubuntu 12.04 + Gstreamer 1.0 via Gems 2.x. При включении звука/видео падает

[Michael Galyuk]

Если Gstreamer 1.0 установлен через Gems 2.x, то при попытке инициализировать микрофон, пандора падает:

"Cannot create gstreamer element "alsasrc""
"Cannot create gstreamer element "audioconvert""
"Cannot create gstreamer element "audioresample""

Проблема решается если ставить Gems 1.x и Gstreamer 0.1,
также всё хорошо, если ставить через пакетный менеджер Synaptic.
