Invalid branch name

[knobik]

When im using

$branches = $repository->getBranches(false, true);

im getting this error

the branch string is not valid: remotes/origin/HEAD -> origin/master
/vendor/cypresslab/gitelephant/src/GitElephant/Objects/Branch.php:199

    public static function getMatches($branchString)
    {
        $matches = array();
        preg_match('/^\*?\ *?(\S+)\ +(\S{40})\ +(.+)$/', trim($branchString), $matches);
        if (!count($matches)) {
            throw new \InvalidArgumentException(sprintf('the branch string is not valid: %s', $branchString));
        }

The corresponding code has been altered in the meantime. Is this error still reproducible?
