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.

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
