title: Error when try installing budspencer theme for fish shell
body: <p><strong>My fish conf (.config/fish/config.fish)</strong></p>
  
  <pre><code>set -e fish_key_bindings
  set -U fish_key_bindings fish_vi_key_bindings
  set fish_path $HOME/.oh-my-fish
  set fish_theme budspencer
  . $fish_path/oh-my-fish.fish
  </code></pre>

  <p>if I remove theme and sets result in:</p>
  
  <pre><code>  desenvolvimento@dp-inf015:~$ fish

  <p>If I uninstall fish, oh-my-fish and all file conf and install again, error keeps happening...
  How I can solve this?</p>
