Same as in previous patch: no additional signal needed.

Now that I think of it, I think 'custom_conf' would be a better name
for this parameter. Same for the previous patch.

Same here:

if(flags || custom_xml != NULL)

Oh and now I realize that you are checking for the string extracted
from the parameter for being NULL. You want to check 'conf' itself to
be NULL here and then extract the XML string before using it. You'll
wan to remove one of the g_return_val_if_fail above to allow user to
pass NULL as conf.

Same goes for the previous patch too.

Since we are using essentially the same data as for
gvir_connection_domain_save, I think we can simply re-use that:

#define DomainRestoreFromFileData DomainSaveFromFileData

Same goes for this function.

Possible coding-style issue here as well.

Same warning about tabs.
