I just installed brand new Linux Mint 14 w/ Mate and I used sunab's repo, deb http://ppa.launchpad.net/sunab/kdenlive-release/ubuntu quantal main, to install kdenlive. Every time I open kdenlive I get the following error; "File /home/daniel/%i is not a Kdenlive Project File".
It's very irritating, can anyone inform me how to get rid of it? I have tried to rerun the config wizard and also looked into the kdenlive settings.

On a side not, how do I enable libx264 rendering? When I was using Ubuntu 10.04.4 I enabled the medibuntu repo I believe to get the "-"-extras" libraries enabled for ffmpeg. What do I now that I am in Linux Mint 14 w/ Mate? Thanks

The "is not a Kdenlive Project File" error message probably pops up because you have enabled the "Open last project on startup" in Kdenlive Settings > Misc, and something is corrupted in your Kdenlive config file.

Either try to uncheck the "Open last project on startup" option, or delete your kdenlive config file: $HOME/.kde/share/config/kdenliverc

For the x264 rendering, not sure but how it works with mint, but Ubuntu Quantal provides libav*-extra packages and also a x264 package...

thanks!

I have a fresh install on a fresh machine (linux Mint16 mate) and I get the same error "File /home/matt/%i is not a Kdenlive project file" the very first time I run the program after the initial install. It is not big problem as it doesn't crash and you just ok the error, but annoying.
- I checked and I don't have the "Open last project on startup" setting checked.
- I have deleted the "kdenliverc" file, this causes you to have to re-initialise your settings on the next start up but then the same error still comes up.

I note that ubuntuaddicted replied with a "thanks", does that mean you found a solution?

Cheers
Matt

Update : I just found a solution, and from the looks of this it has been an issue for a long time, but easy to fix. -> http://forums.linuxmint.com/viewtopic.php?t=60124&f=47

Basically you have to change the linux Mint launch command
from "kdenlive %i -caption "%c" %u"
to "kdenlive"
in the mint menu
