I noticed that some icons in GNOME-applications are missing, so any of
those might do in place of compiz. They all belong to Ubuntu, not guix.

The result of `env LD_DEBUG=libs LD_DEBUG_OUTPUT=/tmp/trace
gnome-calculator` told me that /gnu/store paths are checked first and
exclusively for several libraries.

LD_LIBRARY_PATH is empty and `env | grep /gnu/store` prints nothing,
but env does contain
```
GDK_PIXBUF_MODULE_FILE=/home/thorwil/.guix-profile/lib/gdk-pixbuf-2.0/2.10.0/loaders.cache
GIO_EXTRA_MODULES=/home/thorwil/.guix-profile/lib/gio/modules:/home/thorwil/.guix-profile/lib/gio/modules
LIBRARY_PATH=/home/thorwil/.guix-profile/lib:/home/thorwil/.guix-profile/lib
```

I don’t recall ever doing anything about those; they are not defined
in .profile or .bashrc. I added
```
export 
GDK_PIXBUF_MODULE_FILE=/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders.cache:/home/thorwil/.guix-profile/lib/gdk-pixbuf-2.0/2.10.0/loaders.cache
export LIBRARY_PATH=/usr/lib:/home/thorwil/.guix-profile/lib
```
to .profile. Now I have all icons back! Guess there’s a better way?


This is no longer looks like a guix-topic, but compiz still segfaults
after many errors for various SVGs, like:
```
ERROR 2021-12-28 10:50:18 nux.gltexture.resource.manager
GLTextureResourceManager.cpp:54 Invalid target, impossible to generate
a new texture. Impossible to generate a pixbuf: Couldn’t recognize the
image file format for file “/usr/share/unity/icons/search_spin.svg”
```

`file` and the image viewer eog have no problem with
“/usr/share/unity/icons/search_spin.svg”.

There’s also
```
