Hi, I built my copy of kdenlive from the latest svn revision. It crashes when I exit the config wizard. I have everything installed. I have no idea why it could be doing this!

Kdenlive needs the latest MLT from git. Did you also install latest mlt?
In a terminal, type:

melt --version

What is the output? You should also make sure that your MLT install has all required modules:

melt -query producers
Should at least contain: avformat and xml

and
melt -query consumers
Should contain xml, sdl, sdl_audio, sdl_still and sdl_preview

One last check is to make sure you don't have older MLT libraries installed:

ls -l /usr/local/lib/libmlt* (replace by your install path)

Should only contain version MLT/MLT++ version 0.4.5 libraries

I do have the latest version from git, and I have avformat and xml! I have all of those.

Ok, then you need to test that MLT works correctly. From a terminal, type:

melt myclip.mpg (replace myclip.mpg with one of your video clips)

Can you see the clip playing?

If it works, try deleting the Kdenlive config file at: $HOME/.kde/share/config/kdenliverc

then restart kdenlive

I note you mentioned that "melt -query consumers" should contain various packages, including "sdl_audio". I was examining the recently packaged openSUSE-11.1 kdenlive-0.7.5 and mlt (by openSUSE Packman packagers) which seems to work well, BUT I noted it does not yield "sdl_audio". I then did a search for the package sdl_audio on openSUSE-11.1 and did not find it, nor when I searched the web did I find sdl_audio packaged as an rpm for openSUSE. I did find the developement web page for sdl_audio: http://sdl.beuc.net/sdl.wiki/SDL_Audio

How important is sdl_audio, and what does it provide? I'm asking this as I am pondering if I should ask the openSUSE packagers to package it so that kdenlive on openSUSE can access this.

sdl_audio is in the newly released MLT 0.4.6 and is only used for Mac OS X.
