[Orgmode] org-agende changes mode in buffer to fundamental

[Detlef Steuer]

Hi!

Just trying to start my workday ...

As always the first command is
emacs todo.org

Everthing looks like it should, mode is Org .
But now, if I type 
C-a a 
to view my agenda, mode is reverted back to fundamental.

That also happens if I use
M-x org-agenda
to start it.

Mode line tells me: Agenda file todo.org not in org-mode.
Message buffer: 
org-agenda-get-day-entries: Agenda file ~/.pim/todo.org is
not in `org-mode'
Well --- it was when I called you, org-mode! ;-)


org-version
release_7.4-324-gca7a
Org-mode version 7.4 (release_7.4.324.gca7a)

Any immediate help advice? 
Ok, the lecture starts 9:45 ... but what else was planned for today?
:-)
