Summary

0000755: segfault while playing with placeholder clips

Description

i get some random crashes while playing around with a placeholder video clip (not a slideshow clip), and few times just after loading the project

Steps To Reproduce

1. save a project and close kdenlive
2. move at least one video file contained in the project
3. open kdenlive and load the project: when prompted about the missing file, choose "leave as placeholder"

it could crash now. if not:

4. start dragging between tracks the placeholder clip, and expect a crash

Notes
(0002692) administrator (administrator) 2009-04-09 19:35	Fix committed to svn (rev. 3268)

(0002843) xzhayon (developer) 2009-05-11 13:26	it wasn't enough, crashes were still there just committed another fix to rev. 3372: now i can play with placeholders the mlt::producer wasn't == NULL, so the code after that check was still executed (by the way, how can that be NULL?)

(0002877) xzhayon (developer) 2009-05-17 15:45	fixed in rev. 3372
