Comment 1 for bug 519726

I have the same issue. Here's my terminal output:
user@user-desktop:~$ openshot

Let me add that I have a weird computer that was assembled privately in China. I have system clock issues when the power cuts out or after the computer is unplugged. After a power outage, I restarted the computer and could barely boot into Ubuntu. I had to reset a bios setting (boot order) and after finally getting into Karmic I had to reset my clock. It's possible that the above bug is related to some missing or corrupted configuration file. My other programs work and start just fine. I've already tried the fixes here https://bugs.launchpad.net/openshot/+bug/480894 (purging openshot and mlt, plus the files listed there, then reinstalling).

I'm running Ubuntu Karmic 9.10 and OpenShot was installed through the PPA.
