Comment(by erikos):

 I tried to reproduce the issue outside of Browse, like:
 from gi.repository import Gtk
 list_store = Gtk.ListStore(str, str)
 list_store.append(['hallo', None])
 But we 'only' get a warning there that 'G_TYPE_IS_VALUE (src_type) failed'
 but do not crash. Looking at the trace we bubble up until displaying that
 warning when Browse crashes.

 In any case, we should not feed data in our liststore that we did not
 create it for. There is even a method to check for valid data
 is-valid but we should not use that, it is slow.

 I think we should handle the title and address as ' ' as default inside
 Browse and not None. Our checks for example if we should display
 'Untitled' should be changed from checking if the string is empty instead
 of if the variable is None.
