The good news is this bug is no longer an impediment to installing the
package because I took a(n arguably foolish) risk and disabled the tests
in the package definition (see attachment: rednotebook.scm). The bad
news is this bug persists when I run the installed package. When I
install rednotebook and run it, I get an error like the following:

Looks like this bug infests more than a temporary guix
environment. The program crashes unable to find some essential class
definitions even when I add a directory containing the necessary shared
libraries to $LD_LIBRARY_PATH and check that GI_TYPELIB_PATH has the
necessary typelib files.
