Hi,
I'm not sure how many AV Linux users frequent the Kdenlive forums here but there are updated Kdenlive/MLT packages for AV Linux 6.0 users built from recent GIT that feature VERY significant improvements thanks to J-B-M's recent herculean bug fixing activities. It is hoped that 0.9.3 packages will be available whenever it is released but in the meantime this is a very solid build to use.
Please read and follow the instructions here carefully:

A sincere thanks to j-b-m for being so quickly responsive to bug and build reports :)

Hi Marko.
Thanks very much for your comments and for recommending AV to people. It is fairly well known in Linux Audio circles but I am just as interested in getting the good word out about Video Editing under Linux but that is even a smaller niche. I'm very grateful that some of the issues I was having with MLT and Kdenlive previously are now resolved and that Kdenlive can still be built and run on AV's Debian Stable base.
