Hi!

I wanted to let you know that I rewrote thread handling in Kdenlive. Now, we 
use a maximum of 3 concurrent threads (to create the audio / video thumbnails 
and query a clip's info).

I also just added a check in Kdenlive that will dynamically increase the cache 
size for avformat_producer to the number of tracks + 4, so we should hopefully 
be safe on that side.

Mikko, I would be interested to know if these changes have an influence on the 
crashes you experienced.
