Ok,

I'm quite sure this depends on the changes discussed here:
http://lists.gnu.org/archive/html/bug-gnu-emacs/2013-08/msg00776.html

which (as far as I understand it) means that wrap-prefix (and line-prefix?)
now uses the currently active face (or something like that) instead of
default. The "working" indent in variable-pitch-mode thus depended on
wrap-prefix and line-prefix having the "wrong" (default) face instead of the
variable-pitch face that is now used.

One workaround is to customize the face org-indent in some way to make it
roughly match the width of your stars:

(set-face-attribute 'org-indent nil :family "YOUR_DEFAULT_FAMILY")

This worked ok for me.
Just inheriting default didn't seem to work. I think that is overridden by
variable-pitch mode.

I don't know if this could be generalized in a good way that could be put
into org-mode since the desired width (or family) depends on each users
configuration.

One possibility could be if it would be possible to get the pixel-width of a
star in some way and then set line-prefix to a correct pixel-width (multiple
of this).
