This is how I got Openshot to work on Arch where we're having libfontconfig issues. The current workaround for the issue is to remove libfontconfig.so.1 from the openshot appimage. The basic steps are:
1) extract openshot appimage to a folder
2) delete libfontcongif from /usr/bin
3) recreate appiamge with appimagetool

To do this you will need appimagetool which can be downloaded here (https://github.com/AppImage/AppImageKit/releases)

1) extract appimage:
Openshot is a type 1 appimage, meaning it can't be extract by adding --appimage-extract to the command line which only works for more recent type 2 builds. So I had to mount the build using
sudo mount -o loop .AppImage /mnt.
I then created a folder with the same name as the Openshot images I downloaded minus appimage and added .AppDir so I ended up with something like .AppDir.
Next copy everything from the mounted image to the new folder.
2) delete libfontcongif:
cd to .AppDir/usr/bin and remove libfontconfig.so.1.
3) recreate appiamge:
Last rebuld the appimage with appimagetool-x86_64.AppImage .AppDir

The new appimage should now work.

Finally umount the loop

@jigalvez - Just for the sake of posterity, how did you remove libfont from the package? Just in case someone else needs to take a look at this. Or do you mean you did $ sudo apt remove libfont? Sorry for being such a tube-light.
