After loading ImageView, emacs (e.g. on Ubuntu Linux 20.04 with X11) started from within Julia (REPL shell mode) no longer works:
$ julia
shell> emacs
julia> using ImageView
shell> emacs
(emacs:11056): Gtk-WARNING **: 15:00:06.174: Could not load a pixbuf from icon theme.
This may indicate that pixbuf loaders or the mime database could not be found.

Gtk:ERROR:../../../../gtk/gtkiconhelper.c:494:ensure_surface_for_gicon: assertion failed (error == NULL): Failed to load /usr/share/icons/Tango/24x24/status/image-missing.png: Unrecognised image file format (gdk-pixbuf-error-quark, 3)

This appears to be caused by some GDK_PIXBUF_* environment variables that ImageView sets globally, which also affects other GDK applications invoked from within REPL shell mode:
$ julia
shell> bash -c 'env >a'
julia> using ImageView
shell> bash -c 'env >b'
shell> diff a b

After loading ImageView, emacs (e.g. on Ubuntu Linux 20.04 with X11) started from within Julia (REPL shell mode) no longer works:
This appears to be caused by some
GDK_PIXBUF_*environment variables that ImageView sets globally, which also affects other GDK applications invoked from within REPL shell mode:As a result, emacs no longer can find its icons.
