In case anyone face the same issue :

Search for any "*.info" file in your drupal repo that has no line similar to "name = xxxx".

The "*.info" file might be outside of your themes.

For instance, my problem was due to a file named "lcov.info" in a grunt module (grunt-svgmin) in my theme. I happended "name = lcov is not a theme" at the beginning of the file and the issue fade away. I'll check svg-min later.
