This error is coming from the scss compiler and is likely due to an
error in one of horizon's scss files. The scss files have undergone
substantial changes since this bug was reported, including the bootstrap
update (https://review.openstack.org/#/c/107042/). Closing this bug
since it is likely no longer relevant. Please reopen if it happens
again.
