Hi 

It took me a good hour to find the package that produced the problem.
It's org-depend. I narrowed down my .emacs to a minimum:

(add-to-list 'load-path "~/elisp/org")
(add-to-list 'load-path "~/elisp/org/lisp")
(require 'org-install)
(add-to-list 'load-path "~/elisp/org/contrib/lisp")
(require 'org-depend)

(setq org-agenda-files (list "~/myconf/mygtd.org" "~/myconf/googlecalendar.org" "~/myconf/from-mobile.org" "~/myconf/diary.org" "~/aktuell/orthodoxy/hab-diary.org"))

(global-set-key "\C-ca" 'org-agenda)

When I comment out the fifth line (require 'org-depend), everything is
fine. With org-depend loaded, a "org-tags-view keywords={Something}"
affects the buffers of some of the open org-agenda-files. I still don't
know why only some files are affected. It happens only if actually some
matches are found by the query. But it's not only the corresponding
files which are corrupted.

So, I think org-depend needs some revision. It's a useful package, but
this bug is annoying.

P.S. I had updated to the latest stable version of orgmode, so it's not
an obsolete bug.
