launch-openshot cannot find python module 'openshot'

I am running Ubuntu 15.10 and have installed openshot-qt from the libopenshot-daily ppa.
When I try to start openshot via the launch-openshot command or from the Unity launcher "OpenShot 2.0" it crashes with:

Loaded modules from installed directory: /usr/lib/python3/dist-packages/openshot_qt

Workaround:
The first line of launch-openshot is #!/usr/bin/python3.5, the python module however is installed in /usr/lib/python3.4/dist-packages.
When I change launch-openshot to use python3.4, the module is found and openshot launches.

Installed versions:
openshot-qt: 2.0.0+0+504+85+201601102218ubuntu15.10.1
python-libopenshot4: 0.0.6+0+492+85+201601102202ubuntu15.10.1

Hmmm... this seems like a simple solution. I wonder if I can generically use #!/usr/bin/python3, which would probably fix it also. Maybe give that a try, and see what happens. Thanks!

Okay, it looks like I am already using #!/usr/bin/env python3 at the top of launch-openshot. Also, the version should be 2.0.4, and not 2.0.2. I'm thinking you have an older version, and need to update and try again. Fingers crossed. =)

I updated (or rather removed and installed again) to version 2.0.4+0+510+86+201601120649~ubuntu15.10.1

The first line of /usr/bin/launch-openshot in this package still says #!/usr/bin/python3.5, though.
I have looked in the .deb files at https://code.launchpad.net/~openshot.developers/+archive/ubuntu/libopenshot-daily/+packages and the one for vivid (15.04) has (the correct?) #!/usr/bin/python3.

Unfortunately I don't have that much experience with Debian packaging, so I can't tell where this needs to be changed.

I looked at the buildlog on launchpad some more and it seems that under 15.10 wily pybuild calls setup.py with python3.4 and also python3.5 and setuptools then rewrites the shebang line to the calling python version.
