Unable to use M-Ret from line-wrapped relative time items

Hi,

I am an inexperienced org-mode user, so my apologies if this bug report 
falls short, or is submitted to the wrong forum.

I've been experiencing an annoying bug/break since upgrading to OrgMode 
7.5. I'm running it on GNU Emacs 22.3.1 (i386-apple-darwin9, Carbon 
Version 1.6.0).

When I am using a relative timer, I can usually hit M-Ret at the end of 
the current item, to create a new time-stamped item (I'm using [X] for 
point):

- 0:02:04 :: foo[X]

This leads to a new timestamp item:

- 0:02:04 :: foo
- 0:02:06 ::

But when the text of the second note gets to be too long, Emacs wraps 
the text to the next line (I have the Fill minor mode active). Trying to 
use M-Ret from the end of the second line of the second item leads to 
the attached break/backtrace:

- 0:02:04 :: foo
- 0:02:06 :: bar bar bar bar bar bar bar bar bar bar bar bar bar bar
              bar[X]

Any ideas on how to fix this bug/break? Do I merely need to upgrade my 
version of GNU Emacs?

Thank you for your time & help,

~Tomer
