Yade closes when launchıng

Hi there,

I am a new user and I was able to compıle yade from source fıles (git clone https://github.com/yade/trunk.git) but when I try to launch it (./yadeExecutableFile), I get this message and Yade closes:

    'char must be Config instances: %r, %r' % (key, value))
ValueError: values whose keys begin with an uppercase char must be Config instances: 'in_template', 'Yade [\\#]: '

I work on Ubuntu 16.04.2 LTS.

I guess ıt ıs related to python but I don,t know how to fix this. Could you please help?

Thanks
