Preview playback no longer works following upgrade to karmic

Bug Description

Binary package hint: kdenlive

I have been using kdenlive to edit movies recorded using my samsung F34 flash-based camcorder for some time now, and it has been working fine.

However, since upgrading to Karmic, it no longer works. I can import the clip fine, but when I try to playback it freezes shortly after starting and completely locks up kdenlive. Only a kill -9 gets rid of it at that point.

The clips play fine from some standalone players such as smplayer, kplayer, kaffeine and totem

However, in VLC, playback is a little choppy. I don't remember it being like this before the upgrade.

The clips are encoded as follows:


720 x 480
H.264 / AVC
30 frames per second


MPEG-4 AAC audio
24000 Hz

Any hints, tips or pointers would be appreciated.

I am also affected by this, I might try installing an older version to see if that helps.
