I noticed a regression in the capture functionality after upgrading org.
Capture fails with error in subj
Here is a simple config to reproduce the problem and a patch that fixes it.
emacs -q -l capfail.el
Best,
Alex

After I replaced my patch and merged Bastien's fix, I started seeing the
error though less frequently than before. It didn't occur in the template I
posted, but I started seeing it again in another template.
("w" "org-protocol tag" entry (file "~/org/bookmarks.org")
"* %:description %(org-set-tags)\n %i\n\n %:link\n%?"
:prepend t :empty-lines-after 1 :clock-in t :clock-resume t)
I switched back to my initial patch that was checking if the mark was set
before trying to access the region. This worked: the errors disappeared.
However, I couldn't understand why mark would be unset in the first place.
It turns out that this is a result of the function
org-capture-steal-local-variables that is copying mark-active variable from
another buffer. This results in an inconsistent state where mark is not set
and yet the variable mark-active is set. Emacs functions region-active-p
and use-region-p expect the state to be consistent and fail with this error
that they won't produce under normal circumstances. Here is the minimal
patch that fixes the root cause of this problem:

If I may ask, why using %(org-set-tags) instead of %^g or %^G?

I think the right fix is to exclude `mark-active' from the local
variable that are imported through `org-capture-steal-local-variables'.
I installed such a fix in maint, please update Org and let me know if
this works for you.
Thanks,

I am using org-set-tags to avoid autocompletion, both %^g and %^G take too
much time because my org files have many tagged items. Capture should be
fast to be effective.

Excluding mark-active will work, the result will be the same as after my
patch, except performance will not be the same. Excluding variable requires
filtering the list of variables which takes O(n) whereas my patch takes
O(1). Mark-active is nil before org-capture-steal-local-variables because
this is a new buffer. It seems in this case setting it back to nil is
faster than trying to preserve its original value nil.

I see what you mean but there is no performance issue here and not
copying the value of mark-active is cleaner than setting it back to
nil -- we never want to copy the value of the mark at all.

In fact, there is some performance issue. The steal function copies a lot
of variables as I can tell. Do you know where those variables are used? I
replaced the steal function with an advice like this
(defadvice org-capture-steal-local-variables (around do-not-steal activate))
My capture became very fast after that and I didn't notice any adverse
effects so far (using this for more than a week). The only reason I didn't
propose a patch like this is that I am still testing it for possible
regressions.

This is what I observe (using elp-instrument-function on
`org-capture-steal-local-variables' and calling org-capture
10 times):
A: org-capture-steal-local-variables 10 0.005087601 0.0005087601
B: org-capture-steal-local-variables 10 0.0028751399 0.0002875139
A difference of 0.2 ms is not really perceivable.
Do you get difference results?
