GIO criticals from unset GFileInfo attributes
These have been showing up in random places, ever since gio was 'improved'...
(flatpak install:5947): GLib-GIO-CRITICAL **: 08:15:06.629: file ../gio/gfileinfo.c: line 1800 (g_file_info_get_size): should not be reached
We really have to be more careful about these things. Glib is used everywhere, and patching up the world for such things is not fun and will only give people the idea that GLib isn't something to rely on.
