AppImage has a missing dependency on Fedora 32

[Ilgaz]

Hello,

I downloaded XnView appimage and made it executable, it didn't work when clicked from Gnome Files (fedora 32 current).

When you try to launch from Terminal, a message appears saying libnsl is missing. So when I installed libnsl via RPM, it works.

I guess libnsl should be included in appimage.
