Are you sure that you are typing the class name properly? It should be

class :Image:Description from G:Object

Given you have an empty namespace, or if your namespace is Image, just make
that Image:Description. It seems like you have typed GObject and not
G:Object. gob doesn't know any glib types by name and you must always use
the namespace/word separators for everything to work. That's the only way
gob can generate all the other "names" for a type. Read the section of the
manual on type names.

It is maintained, though not improved recently. Gob is relatively simple in
that it doesn't really need much updating. There are missing features which
"would be nice" given enough hacking time such as defining interfaces
(currently you have to define interfaces by hand, though you can have your
class implement interfaces through gob).
