[Kdenlive-devel] Can't start kdenlive

[<cda...@je...>]

Hallo all
Recently I updated ffmpeg from 20060814-0.4 to 20070106-0.1 (marillat 
packages) and now I can't open kdenlive. What I get in console is:
kdecore (KAction): WARNING: KAction::insertKAccel( kaccel = 0x8274a20 ): 
KAccel object already contains an action name "edit_paste"
kdenlive: Mlt inited

Failed to load plugin: libavformat.so.50: cannot oper file of shared 
object: file or directory doesn't exist
KCrash: Application 'kdenlive' crashing...

In kde debuging tool I get:
...
#5  0xb7f8282c in mlt_properties_set_int () from /usr/lib/libmlt.so.0.2.2
#6  0x00000000 in ?? ()

I have tried installing back ffmpeg 20060814-0.4 but no result. Any idea?
Thaks in advence
