Hmmm. This sounds like a very narrow minded decision to me. I have been planning to write write a framework where one can send GtkBuilder XML snippets to a DBus service and have that service embed this as out of process plugins. The described GtkBuilder behavior forces me to write a separate validator before I pass it to the GtkBuilder. Bugger. Cheers, Mikkel
