gitinspector.py --version reports "Error processing git repository ..."

[jamesquilty]

On the current Master commit, 15 May 2017 (6d77989e341e043c9a7f09757000d75701b32d84), trying to obtain the version using the --version flag produces an error:

$ gitinspector.py --version
Error processing git repository at "...".

The 0.4.4 release produces a more expected result:

$ gitinspector_044.py --version
gitinspector 0.4.4

This is a minor bug, but it would be useful if it could be fixed because I am running multiple versions.

Thank you @jamesquilty. I guess we have a regression in there. Will take a look when I have time.

Some more information: when run from a directory which contains a .git folder the expected output is produced:

$ gitinspector.py --version
gitinspector 0.5.0dev
