Dear all,

I am working on a Hdv720p movie.

Segfaults happen when deleting a movie, either in the timeline OR in the project tree.

I will post several examples below.

As usual, this is always latest Debian SID with latest MLT + Kdenlive SVN.

Kind regards,

Jean-Michel

If I move timeline cursor to the end of the timeline, kdenlive segfauts.

project:

         Use the -dograb option to enforce grabbing.
