I stumpled on this infinite loop by accident and simply avoid it by
make my function refuse to work on a buffer not in org-mode.

However, I decided it worth a bugreport as I didn't know the reason
for this and assumed org-mode may enter this loop by itself if the
right conditions are met.

After debugging the loop it turns out that the loop occurs in
`org-insert-property-drawer' because `org-keyword-time-regexp' is
buffer local only (calculated when entering org-mode) and defaults to
nil, so when `org-insert-property-drawer' tries to skip SCHEDULED,
DEADLINE etc. lines it tries this by while-re-search-forwarding[1]
with the regexp "^[ \t]*" -- that is what throws Emacs in this loop
(for whatever reason -- I hope I am going to find out).

So the question is: Is it in anyway possible that
`org-keyword-time-regexp' is (re-set to) nil in regular orgmode
operation? 

As far as I could see: No, so it should not effect the normal
operations of org-mode.

Regards,

[1] i.e.: (while (re-search-forward "^[ \t]*")) causes Emacs to
loop. That means "not beeing in orgmode" not even a sine qua non for
this loop.
