Unable to filter agenda to show only non-tagged items

Unable to filter agenda to show only non-tagged items

[sgeorgii .]

Hello!

Having installed latest org 8.3.2 I am now having the subject problem:

M-x org-agenda

When in agenda:

/ (filter)

TAB (filter by tag)

<Enter> (without entering any tags for "Tag:" question)

Before this gave me agenda view filtered to show only non-tagged items.
I believe this was right and just fine.

Now I have error:

Debugger entered--Lisp error: (args-out-of-range "" 0 1)
  org-agenda-filter-make-matcher-tag-exp(("+") 43)
  org-agenda-filter-make-matcher(("+") tag t)
  org-agenda-filter-apply(("+") tag t)
  org-agenda-filter-by-tag(nil)
  call-interactively(org-agenda-filter-by-tag nil nil)
  command-execute(org-agenda-filter-by-tag)

I am using the latest org package available via package manager as of
this morning.

Any help?

I believe 6c6ae99 (org-agenda: Filtering in the agenda on grouptags,
2015-01-24) changed this behavior.  The discussion about these changes
is here (sorry, the gmane web interface is down for me):
https://lists.gnu.org/archive/html/emacs-orgmode/2015-01/msg00618.html

org-agenda-filter-by-tag should be fixed to handle the empty tag case
that causes the error above, either by behaving as before or by giving a
clear error.  I haven't looked closely enough at the changes or the
discussion to guess whether that commit intended to preserve the empty
tag behavior you were relying on.  Is that behavior documented anywhere?

Thank you Kyle. I wrote to that tread - hope they might be able to help me.
Regarding the above behavior being documented - I believe not. The
reason I believe it does not require specific documentation. Because
this is default behavior to filter by empty tag. How else would one
filter to get only non-tagged items in agenda? This way came to me
naturally and I used it ever since until it stopped working in recent
version of Org. Hope someone could get this use case incorporated or
advice on another way of filtering only non-tagged items in agenda.
