Comment (by sreedoap):

 Alright.. I've compiled below a complete list of steps to reproduce. Turns
 out this only will happen if there is a plugin activated that uses the
 is_front_page() function.

 1) Change the URL of the site to have uppercase characters (for example
 testsite.example.com to TESTSITE.example.com)

 2) Change the permalinks setting to an option besides the default (for
 example post name)

 3) Install the following plugin:

 4) Attempt to access the sites homepage, a infinite redirect loop will
 occur.
