In the past (http://article.gmane.org/gmane.emacs.orgmode/79803/) I had a problem with pushing using org-mobile, and it was solved as detailed in (http://thread.gmane.org/gmane.emacs.orgmode/79856/focus=79876). Indeed now the patch can be found in ELPA, but it still introduces the same problem as reported above. 

My setting is:
Emacs  : GNU Emacs 24.3.1 (x86_64-apple-darwin, NS apple-appkit-1038.36)
 of 2013-03-13 on bob.porkrind.org
Package: Org-mode version 8.2.4 (8.2.4-3-g7fe99a-elpa @ /Users/drorata/.emacs.d/elpa/org-plus-contrib-20140217/)

Line #463 in org-mobile.el is:
((eq (car x) :grouptags) nil)

which should be the fix. I could fix the issue by moving this line after the following one, have:

((eq (car x) :newline) nil)
((eq (car x) :grouptags) nil)

for lines #463-464 instead of 

((eq (car x) :grouptags) nil)
((eq (car x) :newline) nil)

which is the current state.

Can someone verify this?

Best,
Dror
