Can somebody please help me to get kdenlive working on my system?

When I try to start kdenlive from either the terminal or the gui I get a brief flash of a dialog or splash screen (it's very fast) and then nothing. On the terminal it just returns to the command prompt with no messages of any kind.

I'm using kubuntu 12.04 with kde 4.9 from backports.

I started with the standard ubuntu repository when that didn't work I did the following which I found in a post in this forum:
1) remove all MLT / Kdenlive packages:
sudo apt-get remove kdenlive libmlt* melt
2) make sure you have added the sunab repository:
sudo add-apt-repository ppa:sunab/kdenlive-release && sudo apt-get update
3) re-install kdenlive:
sudo apt-get install kdenlive

Both standard repository and sunab give me the same result.

after sunab apt-cache policy gives me:
kdenlive:
Installed: 0.9.2-0ubuntu0~sunab~precise2

Please help me trace this.

Did you ever get this figured out, as I'm having the same problem. What did you do to solve it?

Thanks,
Doug

Can you try running kdenlive under gdb to see if it is crashing in any way?
Console output is usually helpful as well here, so please enable all debugging areas, which can be done by running "kbebugdialog" and following the prompts.

can you try without kde 4.9 from backports possibly? I am running xubuntu 12.04.3, using sunab kdenlive-release ppa and my kdenlive is running perfectly and I believe it's 0.9.6.

something is definitely wrong when you're saying that sunab's kdenlive-release ppa is giving you 0.9.2-0ubuntu0~sunab~precise2 , i can see on the ppa website it says 0.9.6 for precise. in fact lucid is even on 0.9.4-0ubuntu0~sunab~lucid2.

after you switch or add your sunab's ppa within your package manager are you ensuring you click up update repositories? i know when I was switching back and forth from sunabs release and svn ppa's I would always use synaptic and would search for melt and mlt and ensure i got rid of the currently installed version.
