Is this the appimage from aferrero2707 GIMP_AppImage-release-2.10.8-withplugins-x86_64.AppImage ?
Just been checking it out and I do not think you will get nufaw working in that. Tried it and no-show. The Gimp developers cannot see much past Rawtherapee and Darktable.
The appimage will support Carmelo's own application Photoflow (I dislike that as much as Darktable) You could try that or one of the other two.
I keep my old homemade appimage around for nufraw and gutenprint because it works. Do not need cutting edge for that.
So that is one solution, keep your old appimage for when needed. I have lots of appimages for all sorts of things. I store them no where near the system files or my home partition. Run them when required.
edit:
Photoflow is probably the closest to nufraw, if you can find a package for your version of linux.
I think you are using Mint so there is a version here: https://launchpad.net/~dhor/+archive/ubuntu/myway
Tried in a 'buntu VM and the installation is quite sizable, pulls in 17 dependencies so more than a few MB's
Using the 2.10.8 appimage
File -> Open a raw in Gimp and it finds Photoflow which opens. YAOBT (yet another obnoxious black theme)
looks like this https://i.imgur.com/B5mDL4P.jpg
..then close Photoflow , a bit of a delay while it thinks, and the image opens in Gimp, as 32 bit fp. https://i.imgur.com/r7Li8fy.jpg
