Ian,

I can't reproduce this here.  Could your try to edebug the functions
`face-spec-set-2' and `face-spec-recalc' to find out why (or better how)
in the trace

>  >   face-spec-set-2(default #<frame emacs <at> baso 0x10107a0> ((t :stipple
> nil :background "#ffffff" :foreground "#000000" :inverse-video nil :box
> nil :strike-through nil :overline nil :underline nil :slant normal
> :weight normal :height 90 :width normal :foundry "unknown" :family
> "DejaVu Sans Mono")))
>  >   face-spec-recalc(default #<frame emacs <at> baso 0x10107a0>)
[...]
>  >   face-spec-set-2(default #<frame emacs <at> baso 0x10107a0> ((t (:stipple
> nil :background "DarkSlateGray" :foreground "wheat" :inverse-video nil
> :box nil :strike-through nil :overline nil :underline nil :slant normal
> :weight normal :height 121 :width normal :foundry "unknown" :family
> "DejaVu Sans Mono"))))
>  >   face-spec-recalc(default #<frame emacs <at> baso 0x10107a0>)

the function `face-spec-set-2' is called alternately with different
backgrounds.  That is, edebug these two functions, call C-x 5 2 or
whatever you have to make a new frame, and tell me whether

(1) `face-spec-recalc' in one and the same call invokes
    `face-spec-set-2' at least twice (where an invocation should cause
    `face-spec-set-2' to really call `set-face-attributes'), or

(2) `face-spec-recalc' is called at least twice when making a new frame.

Please complain immediately whem my recipe is unclear.

Thanks in advance, martin.
