That was indeed the problem.

The account I use for building images runs with umask setting 0027, which means that the files from Github feeds all have 0640 / 0750 permissions. It turns out many files are simply copied to the build directory without changing permissions. This means that if a file or directory on the build system has 0640 / 0750 permission, the permissions in the image will also not be world readable. Previously, this was not an issue, as the permissions were always changed to a 0755 / 0644 (with the exception of some files), but now this no longer is the case, it breaks packages.

This cause my /etc directory to have permission 0750 and likewise LuCI was throwing an error, as lots of files didn't have world readable permission. I'm not sure I like this new behavior. At least people should be warned that they need to checkout the Github feeds with a umask setting not more strict than 0022, in order to prevent this from causing problems in the images.
