I think this is a Python 2.6 feature (i.e. the 'with' command), which is
used by our Vimeo upload feature. If you don't mind editing the .py file
that reported the error, let's try this and see what happens. Open up
the "/usr/lib/pymodules/python2.5/openshot/uploads/vimeo/convenience.py"
file, and just remove the entire "def upload()" method, which contains this
incompatible Python 2.6 code. Of course, this will break Vimeo uploading,
but I think OpenShot might launch correctly. If that does fix it, I'll need
to make some changes to this file in the source of OpenShot and release a
new version to fix this. Thanks!
