[BUG] org-set-tags-command hangs indefinitely in some indirect buffers

[Adam Beckmeyer]

Hi everyone,

In some of my files, org-set-tags-command hangs indefinitely when invoked in an indirect buffer. Attached is an example file where you can see the behavior:

1. Open this file in org-mode.
2. Invoke org-tree-to-indirect-buffer in the "Hello World" heading
3. Invoke org-set-tags-command in the new indirect buffer.

I noticed this problem on git master but bisected and found the bug was introduced by: https://git.savannah.gnu.org/cgit/emacs/org-mode.git/commit/?id=2f7b35ac89470f17937f5c20524c38db103aaa4c

Here's a backtrace when C-g in the middle of the hanging `org-set-tags-command`:

Debugger entered--Lisp error: (quit)

Perfect. Can confirm that bug is no longer present even with my more complex org files.

Thanks so much!
