The listing of the git.yoctoproject.org cgit instance is currently broken in production.
This is due to the use of a no longer valid instance URL (http://git.yoctoproject.org/clean/cgit.cgi/) passed as lister parameter.
The URL parameter must be changed to http://git.yoctoproject.org/ in listing task arguments.
