[Post-Install] man pager glycin::sandbox warning

[jlittle]

For years I have used the MANPAGER environment variable. With 26.04 it has started giving nuisance warnings:

$ export MANPAGER="gvim -geom 99x80 --not-a-term -M +MANPAGER -"
$ man ls
2026-05-08T01:28:02.902164Z ERROR glycin::sandbox: Unable to list root directory (/) entries: Permission denied (os error 13)
WARNING: Glycin running without sandbox.

The man page opens in gvim correctly.

 
$ man ls | ​gvim -geom 99x80 --not-a-term -M +MANPAGER -

is fine.

"Glycin allows to decode, edit, and create images and read metadata." says the project's README. Seems to have nothing to do with man pages.

I know glycin is related to Gnome or Gtk using bwrap (bubblewrap) for sandboxing functionalities, but that is as far as I can understand it. Flatpak also using bwrap for the purpose is a red herring or rabbit hole

Probably not relevant, just adds to my confusion. and not related to gvim (gvim-gtk3?)
