Guys, just wanted to ask if you folks have seen this bug. Basically, we
have an uni-language sites with english shown as the Default in the
language manager (the "star" icon displays indicating that EN is the
default). However, when we query the default language from the Joomla
framework, an empty string is returned.

Selecting EN and clicking the "Default" button in the toolbar fixes the
issue entirely. So basically its an issue where (i) the default language is
not during install and (ii) the default icon displays when it should not.

I have received confirmation from one other dev but thought I'd post here
to see if others have noticed this before going to the bug squad.
