Cool. Just wanted to make sure this was on the radar.

I changed a lot of code around wallets this upcoming version, I'll have to rework imports basically from the ground up, so the code is gonna change completely (and well, work)

Hello. I tried to import a private key from a physical coin somebody gave me. When I finally found the right form for the key, Armory didn't complain but didn't do anything else. Here's what I saw in armorylog.txt.

Code:
2017-01-15 18:35 (ERROR) -- Traceback (most recent call last):

    raise AttributeError("'%s' object has no attribute '%s'" % (class_type.__name__, name))
AttributeError: 'BtcWallet' object has no attribute 'addAddressBulk'

Looking into the code, it looks like this commit is the culprit, with addAddressBulk() removed. I didn't try adding it back because I didn't know if it would upset any proverbial apple carts. Instead, I got 0.94.1 going in a VM, imported the wallet where I wanted the imported key to go, added the key, and exported the wallet back to my primary client. After everything was scanned, the funds were picked up. (The imported key even showed the miner pickaxe. I was pleasantly surprised by this easter egg!)

This workaround isn't perfect, though. I quit Armory and tried to restart. It crashed upon startup. Here's what I saw. It looked like there was a NULL dereference but I didn't save that portion of the report, unfortunately. (Reminder: 0.95.1 on macOS 10.12.2, the latest version.)

Code:
Thread 0 Crashed:: Dispatch queue: com.apple.main-thread
0   _CppBlockUtils.so              0x000000010683e6ef BinaryDataObject Arguments::get() + 31
1   _CppBlockUtils.so              0x0000000106833657 SwigClient::BlockDataViewer::registerWithDB(BinaryData) + 439
2   _CppBlockUtils.so              0x00000001069a4a31 _wrap_BlockDataViewer_registerWithDB(_object*, _object*) + 481

The OS asked if I wanted to try to reopen the window or start fresh. If I tried starting fresh, Armory crashed the same way. Once I tried a reopen, everything seemed fine. Restarting seems fine. I wonder if this has something to do with the wallet integrity scan not being done when I reimported the wallet with the imported key.

Thanks. I'm happy to do any testing if any fixes come up.
