--- Comment #2 from Nikolas Zimmermann <zimmermann at kde.org> ---
Aha, here's the culprit:

nzimmermann at nzimmermann-macbook WebKit % DYLD_FRAMEWORK_PATH=$PWD/WebKitBuild/Debug/ $PWD/WebKitBuild/Debug/ImageDiff actual.png LayoutTests/svg/foreignObject/body-background-expected.png
Error: test and reference images differ in alpha. Test image has alpha, reference image does not have alpha.
nzimmermann at nzimmermann-macbook WebKit % echo $?
1


actual.png: PNG image data, 800 x 600, 8-bit/color RGBA, non-interlaced
nzimmermann at nzimmermann-macbook WebKit % file LayoutTests/svg/foreignObject/body-background-expected.png
LayoutTests/svg/foreignObject/body-background-expected.png: PNG image data, 800 x 600, 8-bit/color RGB, non-interlaced

This is a truly outdated expected.png, dating back to 2012, added by Florin.
I couldn't even remember we generated RGB images in the past...


Anyhow, I'm aware people rarely use pixel tests... will fix this on my own.
