[packagekit] I've broken all your nice backend code...

[Daniel Nicoletti]

Also my backend had a missing symbol
but I was only able to know what was the
error when I added a debug line:
if (handle == NULL) {
		g_set_error (error, 1, 0, "opening module %s failed : %s",
			     backend_name, g_module_error ());
++++       g_debug ("opening module failed '%s'", g_module_error ());
		goto out;
}

Isn't something missing on "out:" perhaps?
