Thanks for reporting this.
It is now solved for the next CB 2.0.5 release (it is also included in latest CB 2.0.4 nightly build (available to all paid members):
www.joomlapolis.com/downloads/downloads-single-items/cat_view/56-advanced-member-download-area
(if you wish to test it and confirm, please Private-message me your email address and we can email you the 2.0.4 nightly).
Alternatively, just rename the .git folder that is at the root of your Joomla folder during installation of CB 2.0.4 release. It can then be renamed back. That .git folder is created by git there because your joomla has been downloaded via git clone (which is ok) and contains the whole Joomla git repository.
