There is a mismatch between the call and the definition of org-agend-format-item:
it recently acquired an extra argument "level" and apparently it is expecting it:

,----
| (defun org-agenda-format-item (extra txt &optional level category tags dotime
| 				     remove-re habitp)
`----

but the call in org-scan-tags does not pass it. So everything got shifted and
when it gets to

,----
| 	(if (string-match org-bracket-link-regexp category)
`----

instead of the category, it tries to do the match on the tags list with
predictable results.

What causes this is not clear however: check org.el:org-scan-tags to make
sure that the call to org-agenda-format-item includes the level argument.
That sounds unlikely however.

My guess is that you missed a step after some update: a remake and
starting with a fresh emacs will probably cure it.
