Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.  You don't know how to make a good report?  See

Your bug report will be posted to the Org-mode mailing list.

org-store-link is not working for Gnus articles, due to the 'To' field
being set to nil in org-gnus-store-link (actually, the relevant field
comes back as nil from gnus-summary-article-header).  M-x org-store-link
calls the debugger with the following backtrace:

The error is occuring when the cdr is taken of '("%T")  -- a patch
follows ... it seems correct to me that the code be made robust in the
presence of a non-cons cell.

I have tested the links generated; they work for the article links I
have tested.
