I get this error when I run `org-mobile-push'. Setting `debug-on-error'
to t doesn't bring up an error buffer when I get this error.

GNU Emacs 24.2.1 (x86_64-apple-darwin11.4.0, NS apple-appkit-1138.47)
Org-mode version 7.9.1 (release_7.9.1-23-gf1f1fc)

I used to get this error when I kept my agenda buffer open for a very
long time. Killing the buffer fixed this. This doesn't seem to work
anymore.

Any ideas?


Cheers,
