It's very difficult to pin the issue down to a guix package being installed.

I imagine the bug would not happen if ~/.guix-profile/share was not in XDG_DATA_DIRS.

Yes, it is related to XDG_DATA_DIRS and it can be tedious to find which
package brings the issue.

I had a similar issue with the package ’python-ipython’ and recently
with ’fontconfig’ – both cases running on the top of Debian.

The issue can happen whatever the profile; it just depends which ones
are sourced by your login shell.

Hello, I don't think XDG_DATA_DIRS should be the problems, but other
environment variables with "lib", since the xdg data should be
portable...

So:
Toggle snippet (20 lines)
$ guix shell -C coreutils zbar --no-grafts -- env
PS1=\u@\h \w [env]\$
TMPDIR=/tmp
TEMPDIR=/tmp
TMP=/tmp
TEMP=/tmp
LOGNAME=iyzsong
USER=iyzsong
HOME=/home/iyzsong
PATH=/gnu/store/yfnm6nh3a6c7hiqk1nq228wpph1x1z1w-profile/bin:/gnu/store/yfnm6nh3a6c7hiqk1nq228wpph1x1z1w-profile/sbin
XDG_DATA_DIRS=/gnu/store/yfnm6nh3a6c7hiqk1nq228wpph1x1z1w-profile/share
GUIX_GTK3_PATH=/gnu/store/yfnm6nh3a6c7hiqk1nq228wpph1x1z1w-profile/lib/gtk-3.0
QMAKEPATH=/gnu/store/yfnm6nh3a6c7hiqk1nq228wpph1x1z1w-profile/lib/qt5
QT_PLUGIN_PATH=/gnu/store/yfnm6nh3a6c7hiqk1nq228wpph1x1z1w-profile/lib/qt5/plugins
XDG_CONFIG_DIRS=/gnu/store/yfnm6nh3a6c7hiqk1nq228wpph1x1z1w-profile/etc/xdg
XCURSOR_PATH=/gnu/store/yfnm6nh3a6c7hiqk1nq228wpph1x1z1w-profile/share/icons
GDK_PIXBUF_MODULE_FILE=/gnu/store/yfnm6nh3a6c7hiqk1nq228wpph1x1z1w-profile/lib/gdk-pixbuf-2.0/2.10.0/loaders.cache
GUIX_ENVIRONMENT=/gnu/store/yfnm6nh3a6c7hiqk1nq228wpph1x1z1w-profile

I think GUIX_GTK3_PATH, QT_PLUGIN_PATH, GDK_PIXBUF_MODULE_FILE should be
the problems.

I had the issue yesterday on Ubuntu. :-)

None of these environment variables were in my profile, IIRC. From my
small experiment, the only common one is XDG_DATA_DIRS. For instance, I
had the issue and I just removed the package ’fontconfig’ which fixed
the issue; the environment variables reads,

Toggle snippet (5 lines)
$ guix shell fontconfig --search-paths
export PATH="/gnu/store/i5rdrrdq4zi98yzcw7rza169ir1zkj6n-profile/bin${PATH:+:}$PATH"
export XDG_DATA_DIRS="/gnu/store/i5rdrrdq4zi98yzcw7rza169ir1zkj6n-profile/share${XDG_DATA_DIRS:+:}$XDG_DATA_DIRS"

The package ’zbar’ also provides XDG_DATA_DIRS. Maybe, I am missing
something.

Just to be sure, do you have default XDG_* environment variables as
configured by guix-install.sh:

Toggle snippet (9 lines)
export XCURSOR_PATH="${XCURSOR_PATH:-/usr/local/share/icons:/usr/share/icons}"
export XDG_DATA_HOME="${XDG_DATA_HOME:-$HOME/.local/share}"
export XDG_CONFIG_HOME="${XDG_CONFIG_HOME:-$HOME/.config}"
export XDG_STATE_HOME="${XDG_STATE_HOME:-$HOME/.local/state}"
export XDG_DATA_DIRS="${XDG_DATA_DIRS:-/usr/local/share/:/usr/share/}"
export XDG_CONFIG_DIRS="${XDG_CONFIG_DIRS:-/etc/xdg}"
export XDG_CACHE_HOME="${XDG_CACHE_HOME:-$HOME/.cache}",

I think their absence used to cause this sort of behavior, since Guix
setting it to something would wholly override the distribution-provided
files.

Hum, no I did not have all these default. It had been introduced after
my install of Guix, I guess. :-)

Maybe we could add a short paragraph/section about that XDG_* variables
under (guix) Application Setup [1]. Although etc/guix-install.sh
already does the correct thing, it could be helpful if people tweak
stuff, I mean, always good to shortly document typical annoyances. :-)

That'd be a welcome improvement! It'd be nice before if you could
confirm/infirm whether this was truly the issue, if you still have
access to the VM.

Sadly, I do not have access anymore to this configuration. I just
remember that I tweaked more than once some XDG_* variables. They
introduced conflicts… I remember one specifically where I was unable to
login under X.

If I am able to replay some scenario, I will propose a paragraph. :-)

Let keep it open for some next weeks and close then since there is not
known issue with the current default provide by guix-install.sh.

Cheers,
simon
