Thank you for looking into this. I have been trying to fix this for a
while and wondered why I did not get the ususal error. I did not look
too far into it because it was late.

I had generated the package definition from a json file I made
(rednotebook.json) so I could generate the package definition by running
`guix import json rednotebook.json`. I did not update the package
definition after I updated guix. The build log looks mostly unchanged.

I went into the environment again and got a different error this time
(rednotebook.log). I started with this error:

RuntimeError: could not create new GType:
rednotebook+gui+browser+Browser (subclass of void)


When I look into the file that defines the Browser class I see it tries
to import the "webKit2" package, version 4.0 which is not defined by
guix. Then it defines a subclass of WebKit2.WebView which Python says
is null.

Luckily there is a warning about what it is looking for:

** (journal.py:2637): WARNING **: 07:12:54.144: Failed to load shared library 'libwebkit2gtk-4.0.so.37' referenced by the typelib: libwebkit2gtk-4.0.so.37: cannot open shared object file: No such file or directory

** (journal.py:2637): WARNING **: 07:12:54.144: Failed to load shared library 'libjavascriptcoregtk-4.0.so.18' referenced by the typelib: libjavascriptcoregtk-4.0.so.18: cannot open shared object file: No such file or directory

This was the error I had before i updated guix. Both of these shared
libraries are in the environment's $LIBRARY_PATH.

Thanks again,
-Jesse
