Zero division error

[GoogleCodeExporter]

What steps will reproduce the problem?

Below steps cannot be directly reproduced since the project it was measured by 
gitinspector is proprietary.

1. Clone gitinspector.
2. Run gitinspector with following options:
python gitinspector/gitinspector.py  --format=htmlembedded 
--localize-output=true --file-types=java,xml,js,properties 
../proprietary-project/ > stats.html

What is the expected output? What do you see instead?

Expected output: generated stats.html file for proprietary-project repository.
Instead ZeroDivisionError was encountered:

Traceback (most recent call last):
  File "gitinspector/gitinspector.py", line 194, in <module>
    main()

    return 100.0 * blamed_rows / changes.get_authorinfo_list()[author].insertions
