"ValueError: 'name' may not contain a dot '.' character" when running capitains-nautilus

[marktani]

I followed the instructions from README:

• Clone the repository : git clone https://github.com/Capitains/Nautilus.git
• Go to the directory : cd Nautilus
• Install the source with develop option : python setup.py develop (this only works after applying PR #93)

Running capitains-nautilus --help works as expected.

However, when I run python app.py or capitains-nautilus --debug ~/my/repository/, I get the following error:
