commit 57e9e886509a04874af6680677c01d34da79ba55

    Fall back to current directory instead of empty name
    
    Comparing two Debian packages directly resulted in an
    empty directory name after stripping the filename,
    while it was searching for dbgsym packages.
    os.listdir tried to open it instead of using the
    current directory.
    
    Closes: #820624
