Unhandled transaction publish failure

[clehner]

I trust a user and the UI shows that the operation completed ("Nice, you trusted ..."), although there remains a spinner in the top-right corner of the window. But no transaction is produced. I look in Network in Developer Tools and see what looks like a request to publish the transaction, failing:

Request: POST https://relay.circles.garden/api/v1/safes/0xc95fCDf549BE356645c16eF0fE48a0558310fECe/transactions/ Response status: "422 No Reason Phrase" Response body: {"exception":"TransactionServiceException: b'\\x08\\xc3y\\xa0\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00 \\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x16Invalid owner provided\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00'"}

Ideally there would not be this error, but in this case the UI should show that the trust operation failed and provide any info about fixing it or an option to retry the operation.
