double spend + blockchain.info => crash

[tlillqvi]

Summary: ArcBit crashes after double spend using blockchain.info blockexplorer API type.
Workaround: use bitpay blockexplorer API.

ArcBit version: 1.4.2 on iOS iPhone 5S
Expected result: No crash

Yesterday I created a transaction with a too small fee by mistake, which lead to it never being processed. To bypass this I copied the private key (via advanced mode) and created a double spend transaction with a higher fee using breadwallet. The double spend went through ok, but I noticed that blockchain.info web page was showing a warning that it was a double spend.
I then transferred the funds from breadwallet back to ArcBit. At this point ArcBit started crashing when opening the Accounts page. ( I assume it got something unexpected from the blockchain.info API )
I tried to "Restore wallet" but that didn't help. I deleted the ArcBit app, installed it again but then it crashed immediately when starting the app using the restore from keychain option.
Finally I managed to get ArcBit up and running again by selecting "start fresh" on startup and changing "blockexplorer API type" to bitpay and thereafter running "Restore wallet"

Keep up the good work. ArcBit is an amazing app. Thanks!
