When opening an experiment programmed in Opensesame 3.1 in Windows on Ubuntu, I get the following error message:

"connect() slot argument should be a callable or a signal, not 'NoneType'"

More detailed feedback says:
"Failed to load plugin 'notepad'

Any idea what could be the problem?

Thanks!

I found that the error message seems to be specific to one Linux installation. On another PC with Linux, the program from Windows worked.

Hi Frouke,

My guess is that you have installed some packages through pip install (which go to /usr/lib/pymodules/), and others through the ppa:smathot/cogscinl repository (which go to /usr/lib/python2.7), with incompatible versions as a result. Could that be it? If you uninstall the pipped version of QProgEdit, do things work again?

Cheers,
Sebastiaan
