[O] Bug: exporting ical files from read-only buffers [7.8.03 (release_7.8.03.112.g8861)]

[Stephen Eglen]

I've found a small bug with exporting ical files from read-only org
buffers.  Create a simple buffer, e.g.:

* test1
  <2012-01-12 Thu>

and then hit C-x C-q to make the buffer read-only.  Then do C-c C-e i
to export an ical file.  You get an error that the buffer is read-only.

I think this is due to the call to org-refresh-category-properties,
which can't update text proprties.  

My workaround is to do:
(setq inhibit-read-only nil)

so that text properties can be added to read-only buffers.  This could
be done locally within the ical export functions if others thought
sensible, for which I can send a patch if desired.
