I tried to reproduce the bug while keeping the following command running on the
terminal:
OAU_LOGGING_LEVEL=2 OAU_DAEMON_TIMEOUT=9999 U1_DEBUG=1
online-accounts-service
And here's the output:

===============
So, in this case (and this is different from Victor's logs, so there might
actually be several different issues here), the plugin correctly emits the
finished() signal. However, the "onDenied" message shows that the account
creation was not completed successfully.
The creation is considered to be successful if the value of "account.accountId"
(where "account" is the object passed by online-accounts-ui to the plugin) is
greater than 0. Looking at the code in the UbuntuOne credentials, I see that
Keyring::storeToken() creates a completely new account, without using the same
account object provided by online-accounts-ui. So, while an account has been
successfully created, it's not the account expected by online-accounts-ui.
It's a mystery why this ever worked. I cannot see any recent changes in
ubuntuone-credentials or online-accounts-ui touching this part of the
code.
Anyway, about how to fix this:
1) the proper solution is to add an account property to
UbuntuOneCredentialsService, which in turn propagates it to the Keyring, which
should then operate on the provided account object instead of creating a new
one.
2) the quick & dirty way is for the QML plugin to call account.store() before
using the Keyring, so that the Keyring will pick up the freshly stored account.
However, in this way we'll be left with a semi-created account in case the
account plugin crashes or aborts the creation, which is likely to cause even
more problems. So, I suggest not going down this road.
