Error: gas required exceeds allowance or always failing transaction

Hi,

We have setup a multisignature wallet and have generated a transaction from this wallet to send 0.2 Ether to one of the owning accounts.
The transaction is mined but in the account of the initiator of the transaction still appears a requiring confirmation.
If the initiator tries to confirm the transaction they get the following error:

Error: gas required exceeds allowance or always failing transaction

At no point was the user requested to setup the gas for the confirmation transaction and there is enough funds in the user’s account to cover for the fees.

Can you please help us understand this issue and resolve it?

Thanks,
Serge
