Gitlab 18.0.0 fails to emerge

Hi,

the current update from 17.11.2 to 18.0.0 fails with the following message:

 * ERROR: www-apps/gitlab-18.0.0::gitlab failed (install phase):
 *   failed to fake the backup path
 * 
 * Call stack:
 *     ebuild.sh, line 136:  Called src_install
 *   environment, line 1685:  Called die
 * The specific snippet of code:
 *       sed -i -e "s|${bp_def}|${bp_sandbox}|g" config/gitlab.yml || die "failed to fake the backup path";
 * 
 * If you need support, post the output of `emerge --info '=www-apps/gitlab-18.0.0::gitlab'`,
 * the complete build log and the output of `emerge -pqv '=www-apps/gitlab-18.0.0::gitlab'`.

The code was recently added in 2dd33d4d

Within the build, the error is a bit more cleary stated:

sed: -e expression #1, char 25: unterminated `s' command
 * ERROR: www-apps/gitlab-18.0.0::gitlab failed (install phase):
 *   failed to fake the backup path

Is there something I need to configure prior to run the update?
