I just grabbed the latest 2.0 code from Github and had to do a DB update. The screen shown after the update (http://localhost/git/dev/Limesurvey/index.php/admin/update/db/continue/yes) contains the following error message:

The LimeSurvey database is being upgraded (2012-06-26 14:54:15) .

Please be patient...

Database update finished (2012-06-26 14:54:16)
