Here is my log file
http://pastebin.com/p3z0BZiYThe private key I attempted to insert (never been used, never will be used, generated using vanitygen for this bugreport) is
5JPW1RT1bwM7GEfx6By3YAh158Yjs6vrphZ3BABLV9DXu4bCdwz
Changes to settings from default:
Unchecked "Let Armory run Bitcoin-Qt/bitcoind in the background"
I started Armory, went online, double clicked on a wallet, Selected Import/Sweep Private Keys, selected "One Key", pasted the key, and selected "Import these addresses to your wallet"
Clicked OK
Verify address, clicked Yes, this is where the traceback appears in the log. Verify address dialog closes and returns me to the Private Key Import form with no change. Address is not imported.
