You're right. The above fixes the issue with fontconfig. Unfortunately,
the problem persists with the minimal manifest:
(specifications->manifest '("python-matplotlib"))
So there's something else going on.
In order to fix the above, I need to put
unset GI_TYPELIB_PATH
in my .profile, after having sourced Guix profile. Maybe this
environment variable also has a special default value when unset.

I think it is desirable, in particular for fontconfig, which is
a recommended package in the manual. The part of Guix responsible for
generating the profile file may be more careful when setting
XDG_DATA_DIRS, e.g., with something like (untested):
export XDG_DATA_DIRS=\
"${GUIX_PROFILE:-/gnu/store/…-profile}/share${XDG_DATA_DIRS:+:}${XDG_DATA_DIRS:-/usr/local/share/:/usr/share/}"
