Warning: Bug in outline-mode: it forgets to call `run-mode-hooks'

I just encountered this error when visiting a .org file and finding I was in outline-mode.
No changes to any of my init files...  M-x org-mode gave the same error.

This error is pretty uncommon apparently, and only occurs under the conditions as listed here:
https://groups.google.com/group/aquamacs-devel/tree/browse_frm/month/2012-01/5da332defbd6a9f0?rnum=211&_done=/group/aquamacs-devel/browse_frm/month/2012-01?&pli=1

In aquamacs 2.4, I found that if I opened a remote file using tramp, and then open an org file either locally or remotely, org mode will fail to start.  If I restart the org mode, aquamacs will report that certain features from outline mode are missing.

The problem can be fixed if one reload the outline library again by hand using M-x load-library: outline, and then restart org mode.

It always happens when tramp is loaded before the org-mode. If a org file is opened before tramp, then subsequent tramp does not break the org mode.

So, there's the cause:

• Calling tramp before org-mode
  (apparently only loads certain pieces of code that makes org-mode think outline is loaded, though it isn't)

And the solution:

• M-x load-library outline
• M-x org-mode,  or normal-mode,  or visit the .org file again

Is it fixed in later tramp / orgmode / aquamacs distribution ?
