It would be my guess that

M-: (face-attribute 'preview-face :height nil 'default) RET

returns "0", which would be clearly an error of the XFT branch.  If
that is the case, please report it to the branch maintainer.

In the mean time, you can try
M-x customize-face RET preview-face RET
and try setting a fixed non-zero integer value for its :height
property (I have the equivalent of 193 on my system, corresponding to
a font that appears to have a height of 19.3 point on-screen).

While preview-latex will then not adapt its image size to changes of
the default font size in your Emacs screens, most people don't
actually change this size.
