openshot deixou de funcionar por problemas com LADSPA

[musinet]

Por favor, moderadores, em tempo, LADSPA não é caixa alta, é dessa forma que o sistema o trata, por esse motivo mantive assim.


Pessoal,

Comecei a usar o openshot e fiquei bastante satisfeito com ele. Porém, estes dias, "do nada" (quer dizer que não fiz nenhuma atualização de sistema entre a última vez que funcionou e a primeira vez que não funcionou), o openshot deixou de abrir. Fui direto para o terminal e executei por lá. Retornou o seguinte:

OpenShot has failed to import some of the Python files or libraries
required for our application to run.  Here are some trouble shooting
tips:

Tip 1) Check if MLT can be successfully imported in Python.  Run the
 following commands, and see if any errors are displayed.  If you get
 an error, you need to investigate the correct way to install MLT.
 NOTE:  Do not type the $ or >> characters in the examples below.

       $ python
       >> import mlt
       >> mlt.Factory().init()

Tip 2) If MLT is working from the first example, then the next tip is
 to look at the above error messages very closely, and google for more
 help.  It's likely the problem is already reported, and maybe there is
 a simple work-around.  Also, you can search for bugs or report a new
 bug at https://bugs.launchpad.net/openshot.  Good luck!

Executei a dica 1:

Não consigo ir mais longe sozinho. Alguém tem conhecimento sobre como resolver?
