[O] Endless loop in org--setup-collect-keywords (agenda, ...)

[Karl Voit]

Hi!

Weird behaviour: yesterday I switched my init.el to OrgStruct and
re-organized it a bit. Silly me thought it would also be a clever
time to update my Org git repo.

At many occasions, my Emacs 24.3.50.1 hangs in an endless loop. When
I break it, I get following Backtrace:

| Debugger entered--Lisp error: (quit)
|   org--setup-collect-keywords("^[   
]*#\\+\\(\\(?:ARCHIVE\\|C\\(?:ATEGORY\\|O\\(?:\\(?:LUMN\\|NSTANT\\)S\\)\\)\\|FILETAGS\\|LINK\\|PR\\(?:IORITIES\\|OPERTY\\)\\|S\\(?:E\\(?:Q_TODO\\|TUPFILE\\)\\|TARTUP\\)\\|T\\(?:AGS\\|\\(?:YP_T\\)?ODO\\)\\)\\):[
  ]*\\(.*\\)")
|   org-set-regexps-and-options()
|   org-mode()
|   set-auto-mode-0(org-mode nil)
|   #[0 "\302\242\237\211\205.
| [...]

(Sorry for the long line)

Do you have a clue if my update or my re-arrangement of my init.el
could have caused this?

Should I check something else?

Thank you very much for your help!
