I'm having this same issue, anyone got any ideas?

I'm having the same issue, think it might be to do with diffing really large pages.

This was a imagemagick issue for me. Although homebrew was telling me that it installed fine, seemingly it wasn't working properly. Only way to fix it for me was to do the following

brew uninstall imagemagick
brew doctor
// Fix all of the issues here, all of them
brew install imagemagick --disable-openmp --build-from-source

I added a check in 6fe0d173e29e5319d3a34b3903ecfd703306f96e to make sure image magick is installed correctly. That should help this one.
