Openshot won't start - installed from PPA

I just received an update to Openshot and after that, receive the exact same error messages. This happened a while back also, and many attempted fixes were suggested here, of which non worked for me. A couple of days later, there was another update, and it started working again, --- until today. The related question and suggestions can be found in question #95857

Look at bug 482985 at:
https://bugs.launchpad.net/openshot/+bug/482985

I deleted mlt.pyc as detailed in my comment there, and using the other instructions there, and Openshot started correctly.

I followed those instructions exactly. I removed MLT, Openshot, and searched and destroyed the mlt.py related files listed.

I still get this error:

$ openshot

I'll done soon two posts (en and fr) in the forum to explain this bug of the Makefile of MLT. And i'm looking actually how to create the binairie for the version 0.4.10. There is no reason that i can not create it, i have already created the 0.44 at the beginning of the creation of the binairies (i hope! ) but here i'm trying the Debian method. I hope that version will resolve this bug.
