I cannot reproduce that here and I don't see how this is possible, the combobox in the properties dialog uses a ThunarChooserButton which calls g_app_info_get_default_for_type() to preselect the default application. So the preselected application in the properties dialog should always be correct and reflect what ~/.config/mimeapps.list contains. The context menu is what should be fixed by this patch (by calling the g_app_info_get_default_for_type() as the combobox does). Have you properly applied the patch before building thunar and are you sure you are actually running the rebuilt version?
If yes, then please provide some more detailed information on how to reproduce this. In particular, temporarily remove ~/.config/mimeapps.list, log out and back in, change the default association of some filetype and then report what the context menu shows, what the property dialog combobox has preselected and what the contents of ~/.config/mimeapps.list are and what your glib version is.

No, the second one is just a refactored version of the first one.
