Hi Dave,

So Gustavo has looked at the problems i had with the new gnome-build
glue-based backend and he came up with the following (he's the man :)

Hi Jeroen,

Well, I found out why we are getting these weird errors.  The problem
arises when the plugin is unloaded.  The g_module_* reference section
says you should never unload a module if the module registers static
data with the rest of the application.  This happens in many places
apparently (though I can only identify the quark registration).

I tried making the module permanent (with g_module_make_permanent), but
then the glue code fails to register the type the second time you ask
for a project object.  I'm not very familiar with the glue code, so
right now I can't tell why.  I'll investigate further tomorrow morning.
In the meantime, if you know how to solve this, I would like to know it
too :-)  Maybe you could mail Dave, as he'll probably know the answer
offhand.

Regards,
Gustavo
