What version of emacs are you running?

The top of the backtrace says

Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p nil)
  indent-line-to(2)
  (if (featurep (quote xemacs)) (org-xemacs-without-invisibility (indent-line-to column)) (indent-line-to column))
  org-indent-line-to(2)

so if the number-or-marker-p applies to the 2, i.e. the argument of
indent-line-to, there is a serious bug in emacs. I assume that that's
not the case - indeed

  (number-or-marker-p 2)

returns t (you might want to try it and verify that that is indeed the
case for you).

If it's something else, then you might want to try evaluating the following:

  (indent-line-to 2)

If that gives you an error, then org is exonerated. In that case, you
might want to load an uncompiled indent.el and step through the function
with edebug (or see if you get a backtrace when evaluating the form
above).

But I must say, this is pretty weird.
