Problem with kdenlive on Kubuntu 8.10

When I was on Kubuntu 8.04, I always used kdenlive 0.5, it's a great program, thanks for making it! But yesterday I upgraded to Kubuntu 8.10 and KDE 4.2 RC1 and now I installed kdenlive 0.7.1 using this: http://kdenlive.org/user-manual/downloading-and-installing-kdenlive/pre-...

But after starting kdenlive, it says that it cannot find the MLT avformat module.

I already tried all the possible solutions in this forum, but the problem still persists. I didn't compile anything that kdenlive requires by hand, I only followed the instructions from your website to install baudm's packages.

Here's the Terminal output:

heimen-at-kubuntu@heimen-at-compaq:~$ kdenlive
kdenlive(1507) MainWindow::parseProfiles: RESULTING MLT PATH:  "/usr/share/mlt/profiles/"
mlt_repository.c, mlt_repository_init: failed to dlopen /usr/lib/mlt/libmltavformat.so
kdenlive(1507) initEffects::parseEffectFiles: //  INIT EFFECT SEARCH
heimen-at-kubuntu@heimen-at-compaq:~$ kdenlive
kdenlive(1914) MainWindow::parseProfiles: RESULTING MLT PATH:  "/usr/share/mlt/profiles/"

kdenlive(1914) initEffects::parseEffectFiles: //  INIT EFFECT SEARCH

How can I fix this problem?
