Does downgrading flatpak fix it?
Comment by Stefano Coronado (stefnix) - Saturday, 05 January 2019, 16:27 GMT
Yes, downgrading to flatpak-1.1.1+3+g4111dbad-1 fixes this issue.

I thought this would be an issue with archlinux-appstream-data based on the program output alone.

Here's a backtrace with a self-compiled flatpak master.
