Hi,

I just updated my RPM package to 0.6.1 and I'm getting this error when
trying to run any of the samples:

$ lua samples/gtk-demo/main.lua
lua: ./lgi/override/cairo.lua:565: attempt to index field '_module' (a
nil value)
stack traceback:
	./lgi/override/cairo.lua:565: in main chunk
	[C]: in function 'require'
	./lgi/namespace.lua:174: in function 'require'
	./lgi/namespace.lua:161: in function 'require'
	./lgi/namespace.lua:161: in function 'require'
	./lgi/namespace.lua:161: in function 'require'
	samples/gtk-demo/main.lua:31: in main chunk
	[C]: ?

I thought it might be something wrong with the package, but I get the
same (or similar) error if I compile lgi and run the samples from the
same directory too. It also happens for lgi 0.6 but not 0.5.

Are there any specific version requirements on GTK/GI?

I'm using:

gobject-introspection-1.32.1-1.fc17.i686
gtk3-3.4.3-2.fc17.i686
lua-5.1.4-10.fc17.i686
lua-lgi-0.6.1-1.fc17.i686

Thanks.
