The current Glade packaged for Guix segfaults when dealing with user interface components like those used in app.ui (https://luis-felipe.gitlab.io/media/2020/09/app.ui). Apparently, the bug is related to the Dialog component.
There is more information about this issue in the bug report I sent upstream (https://gitlab.gnome.org/GNOME/glade/-/issues/479). According to Glade developers, Glade 3.36 is no longer supported, but there are a few fixes regarding Dialogs that went into 3.38 that should cover the issue. Glade 3.38 was released recently. --- Luis Felipe López Acevedo https://luis-felipe.gitlab.io/
