Gstreamer error in rendering .mov and when using pitivi

When trying to open a .mov file video codec: Sorensen video v.3 audio: MPEG 1 Audio, Layer 3 (MP3), I get the following error
Internal GStreamer error: negotiation problem.

Also when executing pitivi, the following error crops up
(pitivi:2162): GStreamer-CRITICAL **:
Trying to dispose object "ffmpegcsp0", but it still has a parent "pitivi+elements+mixer+smartvideomixerbin0".
You need to let the parent manage the object instead of unreffing the object directly.

(pitivi:2162): GStreamer-CRITICAL **:
Trying to dispose object "src", but it still has a parent "pitivi+elements+mixer+smartvideomixerbin0".
You need to let the parent manage the object instead of unreffing the object directly.

Segmentation fault

Other formats are playing ok with totem using GStreamer 0.10.30
