Bug description:
  [Impact]

  Manuskript is an open-source tool for writers. Its main purpose is
  writing novels, books, and the like. It does not have any reverse
  dependencies.

  In Ubuntu 22.04 and presumably all flavors thereof (at least Lubuntu),
  the Manuskript package is currently entirely broken. Attempting to
  launch it from its button in the application menu does nothing, while
  attempting to launch it from a terminal results in a very messy error
  message, which is detailed more thoroughly in the original bug report.
  This renders Manuskript entirely unusable.

  This patch backports the following Git commit to the existing version
  of Manuskript in Ubuntu:
  https://github.com/olivierkes/manuskript/commit/15edb6efb7305b9d1a192712660857ca38facace
  This appears to fix the problem in my testing.

  Those who have Manuskript already installed on their systems currently
  are unable to use it at all, from my testing. Those who have
  Manuskript installed already should be able to use Manuskript again
  after this upgrade is installed.

  [Test Plan]

    1. Install Ubuntu 22.04 or 22.10 into a virtual machine, or use an existing installation thereof.
    2. Fully update the new installation (sudo apt update && sudo apt -y full-upgrade)
    3. Install the current version of Manuskript (sudo apt install manuskript)
    4. Attempt to launch the program from the terminal - the error message described in the original bug report should appear.
    5. Enable -proposed and install the new version of Manuskript from -proposed.
    6. Attempt to launch Manuskript from the terminal - it should launch successfully this itme.
    7. Create a new Manuskript project, make sure that Markdown highlighting works, and 
    8. Attempt to open the saved project. The saved changes should appear.

  [Where problems could occur]

  A typo or malformed line in the patch could potentially result in
  Manuskript being still unable to launch, or cause strange behavior
  with the modified code (which appears to deal with colors, and so
  would likely cause colors somewhere to look wrong). The above test
  plan will catch major failures, and careful checking of the code (by
  making sure my patch matches with the upstream commit) should ensure
  that colors don't end up messed up.

  Original bug report:

  On Wayland it warns about it not liking Wayland before crashing; on
  Xorg it immediately crashes on the unhandled exception:
