Error open pitivi video editor

Hi,

I installed pitivi but when I try to open give me a lot of error.

#pitivi                                                                   
Gdk-Message: 22:30:42.927: Unable to load tcross from the cursor theme
Traceback (most recent call last):
  File "/usr/lib/python3.8/site-packages/matplotlib/backends/backend_gtk3.py", line 43, in <module>
    cursors.SELECT_REGION: Gdk.Cursor.new(Gdk.CursorType.TCROSS),
TypeError: constructor returned NULL

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/usr/bin/pitivi", line 168, in <module>
    _run_pitivi()
  File "/usr/bin/pitivi", line 145, in _run_pitivi

  File "/usr/lib/python3.8/site-packages/matplotlib/backends/backend_gtk3.py", line 49, in <module>
    raise ImportError(exc) from exc
ImportError: constructor returned NULL

Can you help me with that ?

Best regards,

Howdy!
Your best bet for now would be to reinstall pitivi by opening a terminal and executing sudo pacman -S pitivi --noconfirm !

Hope that helps, have a wonderful day!

Wait in the next stable update if it solves the problems… or install the flatpak :wink:

 Packages	   Stable	     Testing	      Unstable	        Repository
 pitivi	       0.999-4	    2020.09.2-1     2020.09.2-1	        community

Aloha, i have also prblems with the the flatpak version. To say with denglish. It’s to milking mice :crazy_face:
