mlt related crash after moving clip on timeline

Notes
(0004049) mcfrisk (reporter) 2009-09-30 22:18	Happened again. Before crash a few clips on one track stopped previewing. Damn, guess I'm not making to freeride.se's video comp..

(0004050) mcfrisk (reporter) 2009-09-30 23:04	After restarting the project kdenlive popped up a complaint along the lines "sorry, producer something producer". Then I removed 15 minutes of material from timeline and cleaned the project. One track was not previewing at all and trying to move clips away from that track resulted in a similar backtrace ending in is_blank(). After restarting and recovering project, the faulty track has lost most of its clips.

(0004051) j-b-m (administrator) 2009-10-01 13:46	I fixed the crash you experienced, but there is something wrong with your project, maybe a corruption in the number of tracks. Could you attach the .kdenlive project file so that I can check the xml?

(0004052) mcfrisk (reporter) 2009-10-01 13:55	Project file attached. It's a monster, created with some kdenlive version in April and edited with a number of svn versions...
