This sounds like a path issue.
Guix
Guix is an advanced distribution of the GNU operating system developed by the GNU Project
If you can, please open an issue on Guix' codeberg issue tracker. This is most likely a packaging issue with GIMP
Do you think there might be missing dependencies? As I'm so new to Guix there is a strong possibility that the problem is due my own oversight or misuse and I wouldn't want to give anyone the run around!
no. this should work out of the box
OK. Will try to find time to make an account and document the problem. Is codeberg the place?
yes, it is.

Just filed a report. Only the first 50 or so characters I write there seem to get actually displayed on the page once posted. Will have to assume that Codeberg afficionados will know how to reveal the rest somehow or I will lose my mind re-posting it!
I've never used gimp so i don't know much about it, but how did you install the plugins? Can gimp read plugins from your home directory? If not it's possible that plugins would also have to be packaged in guix because of some fhs shenanigans.
Yes, gimp can (ordinarily) read plugins from the home directory. It seems that the guix install of GIMP is isolated somehow. I've installed a plugin using guix and that isn't accessible either though, despite both it and GIMP being installed as guix packages.
Hmm, that is weird then. I'm not sure why it would be any different from a regular gimp install at that point. Wish i could be of help.
