1. What exactly did you do?

   I try to use the low-high estimates with the column attribute {est+}
   as documented in http://orgmode.org/manual/Column-attributes.html.

   For that, I tried to assign low and high effort values as in
   http://thread.gmane.org/gmane.emacs.orgmode/93505/focus=93514.  The
   formats I tried:

   :Effort: +4.0-12.0
   :Effort: 4.0-12.0
   :Effort: 4-12
   :Effort: 4:00-12:00
   :Effort: 4:00-1.5d
   :Effort_Low: 4:00
   :Effort_High: 1.5d

2. What did you expect to happen?

   In the attached estplus.org, when I do `M-x org-columns', I expected
   to see the column view with the value for {est+}.

3. What happened instead?

   In the attached estplus.org, when I do `M-x org-columns', I get the
   error 'Invalid duration format'.

   I attach the backtrace as well.
