Hi,

I'm impressed with new Kdenlive.

However, it crashes almost always when I move a slideshow clip to the timeline.

Please file a bug report, i'm not able to register for bug tracker.

Do this,

Open kdenlive > Create Slideshow Clip > Move the clip to timeline > Crash

Hi.

An account using you nick was created Saturday? Are you still not able?

Could this be the same issue as: http://www.kdenlive.org/mantis/view.php?id=310 ?
