Problem after updating org: C-c a a broken

[Markus Heller <hellerm2@gmail.com>]

Hello all,

just pulled from git.

When I type C-c a a to pull up the agenda, I get the error shown below.

This used to work prior to the update.

Org version is 7.7, pulled 5 min ago on emacs 23.3.1.

Help please, can't access my agenda anymore :(

Thanks
Markus
