kdenlive crashing

Hello

I am a Fedora 10 user (x64)

I have compile the last mlt, mtl++, and kdenlive subversion.(For the others dependancies I use the default package provided by yum)

but kdenlive is very unstable crashing after 10 / 15 second of use.( when I drag and drop a video sample for instance )

here is detail error :

Do I miss a depencie or is a package (like qt4 which seems to be in the error stack) not up to date ?

Application: Kdenlive (kdenlive), signal SIGSEGV
