it's not possible to edit the notebookbar.ui file with glade. When I open the file change one thing and save the notebookbar.ui file is broken. without Glade it's not possible to edit the notebookbar.ui file in a usefull way. the other .ui files are no problem.
Which Glade version do you have?
Created attachment 132341 [details] notebookbar.ui only change is cutbox Text beside icons I open the master file and change cutbox from Toolbar Style non to Toolbar Style Text beside icons that's the change but with the new file writer crash.
I have Glade 3.18.3 installed and in preferences I link to /opt/libreofficedev5.4/share/glade the libreofficedev version is master from 04.04.2017.

The original notebookbar.ui file has incorrect structure (id was missing for one element and Glade saved that node but without content).
