Well, regarding this registration stuff I found following mail in Gnome 
archives

gtk input modules usually:
a) don't conditionalize type registration to a static variable
b) use GTypeModule which takes care of your type registration.
so if you're implementing an input module like the rest
of input modules in gtk, you shouldn't get a warning about
type reregistration.

I think that what happens is case a) - type is registered to static 
variable, which seems be something that shouldn't be done...
