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.

In an org file containing timestamps I tried to create a sparse tree
with C-c / D and get an error message regarding eq having only one
argument.  C-c / b and C-c / a  show the same behaviour.

The culprit seems to be this line:

+ '(eq (org-element-type (org-element-context) 'timestamp))
