A lot of frames are dropped during playback after a gap in the timeline

Description
If pitivi plays a clip after leaving an area without any clip then the playback is broken. Frames get dropped in the audio and video tracks, though the effect seems to be independent of each other.
Steps to reproduce:
- Import a video file (DV in our case) and inser it in the timeline at the start
- Playback video, this is smooth
- Move clip away from the start of the timeline
- Start playback from a few seconds in front of the clip
Only restarting pitivi fixes the problem. Adding a black PNG file and a silent audio track in the background of the whole video works around the issue.
Pitivi master (7cbb64f8), and:

Pitivi is slightly patched, eg. to use ximagesink instead of xvimagesink as XVideo is having problems on the machine.
