This sounds similar to the following bug:

https://debbugs.gnu.org/cgi/bugreport.cgi?bug=26202

It has been known for a while that certain environment variables might
cause problems like this if they are not configured "correctly" on a
foreign distribution.  What is "correct" depends on the distro, it
seems.

For more discussion about this kind of issue in general, you might be
interested in the following threads:

https://lists.gnu.org/archive/html/help-guix/2017-05/msg00161.html

By the way, I found those threads by searching for the bug number 26202
on the email list archives:

https://lists.gnu.org/archive/cgi-bin/namazu.cgi?query=26202&submit=Search%21&idxname=help-guix&max=20&result=normal&sort=score

The examples above were specific to Ubuntu and Trisquel (an Ubuntu
derivative), I think.  Perhaps you have discovered a new example of this
kind of problem on Fedora.  I wonder what Fedora is doing with
GI_TYPELIB_PATH that causes this problem to occur for you?
