[Vala] Unregister a GType

[Igor Azevedo <igor azevedo neticle pt>]

Hello,

I'm developing an application that dynamically loads plugins using GModule.
Each of the plugins registers it's own GTypes but if I load, unload, and
finally reload them I get some errors and the modules don't load properly.

Errors are:

(process:21259): GLib-GObject-WARNING **: cannot register existing type
`NeticleInfinityModulesBaseBaseModule'

I understand why this happens, I'm registering a GType that was already
registered previously when I first loaded the plugin and even after
unloading the module, the types remained registered, so it obviously fails.

My question is if there is any way to unregister a GType so I can reload
the plugin successfully?

Thanks,
Igor Azevedo
