It proved that the issue was in the rpc module
implementation related to
handling of the optional specifier '*' when there were no more params
available. I pushed some patches to both jsonrpcs and xmlrpc, but I
could test only with jsonrpcs. Maybe you can give it a try with latest
master and if all ok it needs to be backported as well.
I tried and with latest master ul.add works with or without the last two
opt params.
