Bug description:
  [ Impact ]

  elisa is completely unusable as it will always segfault whenever any
  user tries to launch the application.

  The trace from the coredump showed it was trying to call a vlc api.

  [ Test Plan ]

   * Execute the command "elisa" from a terminal, which will segfault if its not fixed.
   * With the fixed package, the "elisa" window will be displayed.

  [ Where problems could occur ]

   * It is not changing any part of the code, rather its just adding
  vlc-plugin-base as a runtime dependency. So, the chance of regression
  is very less for this.

  [ Other Info ]

  * It was already fixed in 23.04.3-0ubuntu2 of Mantic release.
