Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?
   I tried to evoke handbreak from the Shell and got an symbol lookup error

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
   call handbreak from zsh

   * What was the outcome of this action?
   handbrake: symbol lookup error: /usr/lib/x86_64-linux-gnu/libgtk-4.so.1:
undefined symbol: gst_play_config_set_loop
