The problem here seems to be with the 'italic' face.  It appears that
something in your init is setting that to a different font family either
by assigning the ':family' property or by ':inherit variable-pitch'.

Can you load the theme the problematic way and try:

    M-x describe-symbol RET italic RET

The Help buffer should show something like this:

    Documentation:
    Basic italic face.

    Defined in ‘faces.el’.


               Family: unspecified
              Foundry: unspecified
                Width: unspecified
               Height: unspecified
               Weight: unspecified
                Slant: italic
           Foreground: unspecified
    DistantForeground: unspecified
           Background: unspecified
            Underline: unspecified
             Overline: unspecified
       Strike-through: unspecified
                  Box: unspecified
              Inverse: unspecified
              Stipple: unspecified
                 Font: unspecified
              Fontset: unspecified
               Extend: unspecified
              Inherit: unspecified

Also, what happens after the problematic loading if you re-load the
theme?  Does that affect the fonts or not?

Lastly, did you upgrade between recent versions, say, 1.3.0 to the
current 1.4.0?
