Goose panic

created an issue

I get a panic when running this from a docker container:

root@359dc6646327:/# DB_HOST= DB_PORT=1234 DB_USER=me DB_PASSWORD=abc DB_NAME=test goose --env=default up
panic: runtime error: invalid memory address or nil pointer dereference
[signal 0xb code=0x1 addr=0x20 pc=0x4ab345]

    Probably related to this, walkerr is not being caught:

    / helper to identify the most recent possible version
    // within a folder of migration scripts
    func GetMostRecentDBVersion(dirpath string) (version int64, err error) {
        version = -1
        filepath.Walk(dirpath, func(name string, info os.FileInfo, walkerr error) error {
            if !info.IsDir() {
                if v, e := NumericComponent(name); e == nil {
                    if v > version {
                        version = v
            return nil
        if version == -1 {
            err = errors.New("no valid version found")
