Description of problem:
Pitivi does not work with custom cursor themes under Wayland

Version-Release number of selected component (if applicable):
pitivi-0.98-5.fc25.x86_64

Steps to Reproduce:
1. Set a custom cursor theme with gnome-tweak-tool.
2. Open Pitivi.

Actual results:
This log:
Gdk-Message: Unable to load tcross from the cursor theme
Traceback (most recent call last):

    cursors.SELECT_REGION : Gdk.Cursor.new(Gdk.CursorType.TCROSS),
TypeError: constructor returned NULL


Expected results:
Pitivi working.

Additional info:
I attach my current custom cursor theme "Flatbed Cursors". Please, notice that I'm left handed. I got it from https://gnome-look.org, although it's no longer available. I haven't got this problem with any other application.
Comment 1 Rubén 2017-03-23 23:02:05 UTC 
Solved.
Somehow, this theme is incomplete. To solve this non-bug of Pitivi, change to the cursor theme installation directory and type:

sudo cp cross tcross
sudo cp hand2 hand1

Pitivi then will revive ;)

Regards.
