Confirm payment fails v.0.5.3

I am trying to finalize a trade, however, selecting “confirm payment receipt” is stuck with "sending confirmation …"
The logs show:
[JavaFX Application Thread] WARN i.b.c.t.p.SellerAsTakerProtocol: onFiatPaymentReceived called twice. That should not happen. state=SELLER_CONFIRMED_IN_UI_FIAT_PAYMENT_RECEIPT

I restarted multiple times and tried with my own bitcoind and without.
How can I debug this best?

PS: This sounds similar but wasn’t helpful:

thanks for reporting and investigating!
i just worked on that today and found the issue and fixed it for the next release (not committed yet).
for now the easiest thing to do is to open a dispute with cmd+o and refer to that posting in the arbitration chat. the arbitrator will then do the payout and close the case. security deposit goes back to both traders.

Great, thanks for the swift reply!
PS: I’d also be happy to test the less easy solution.
