Is the ID really missing, or just a copy error ?

I haven't found the bug report in Bugzilla, have you had time to open it
yet or is my search-fu lacking ?
Anyway, this is due to r23345 : since we set the user_symbol of every
currency at startup, the KVP of every currency, even those not used, now
contains simething. Therefore, in gnc_commodity_dom_tree_create(),
kvpnode is !NULL, and every currency gets dumped to the XML file at save
time. That includes the new ZMW, and when your old gnucash that doesn't
know about ZMW sees that currency, it aborts with "Invalid commodity".
I suppose we don't want to dump every currency into the save file
whenever the file is written. Do we want to check currency->usage_count ?
Do we want an API Bool gnc_account_currency_used(Account, gnc_commodity) ?
