** Description changed:

  [Impact]
  
  Users of Carla are unable to refresh audio plugins when more are
  installed, i.e. in the user's home directory. Furthermore, this can
  cause Carla to crash.
  
  [Test Plan]
  
   * Launch Carla
   * Click "Add Plugin"
   * Click "Refresh"
   * Click "Scan"
  
   Expected: Carla will scan for new plugins and find them.
  
   Actual: Carla does not scan for plugins, and may crash.
  
  [Where problems could occur]
  
   * This may simply cause a regression in Carla in which save files may
  cease to load or other issues with plugins loading, however this is
  highly unlikely.
  
  [Other Info]
  
  Originally the plan for this SRU was to upload a patched version of
  Carla 2.4.2 which did not work as planned. 2.4.3 FTBFS when uploaded to
  Kinetic, as did 2.4.4 when uploaded to a PPA built against Kinetic.
  Eventually, it was proven that 2.4.4 would build cleanly in Jammy and
  introduces essential bugfixes, including this fix as well as fixes
  Python 3.10 compatibility issues that were merely patched before.
  
  It is to be noted that this upstream version does *NOT* introduce any
  new features, and the upstream developer was aware that any fixes he
  made in this release could not introduce new features and could only
  introduce bugfixes. As stated from the changelog, these bugfixes,
  including the one in this SRU, include:
  
-  * Fix inaccurate MIDI CC rounding
-  * Fix python3.10 compatibility issues 
-  * Fix integration with internal Qt toolbar visibility state
+  * Fix inaccurate MIDI CC rounding

  Original bug report as follows:
  ------
  
  In the LV2 location in my home directory .lv2 I have the following
  plugin:
  
  ➜ ls ~/.lv2
  librnnoise_lv2.so
  
  ${HOME}/.lv2 is configured in Carla as a search path.
  
  In the Add Plugin dialog for Carla if I search for noise nothing shows
  up.
  
  This worked fine previously on 21.10.
  
  Release notes for Carla 2.4.3 [1] include this line: Fix plugin search
  (regression from 2.4.2)
  
  Ubuntu Studio 22.04 currently has the bugged version:
  
  ➜ carla --version
  Using Carla version 2.4.2
