Bitfinex KeyError instead of Too Many Requests

See original GitHub issue

Environment

OS: Mac
Programming Language version: python 3.6.3
CCXT version: 1.10.566
Exchange: Bitfinex
Method: .fetch_balance()

Error Regular polling of the exchange balance on Bitfinex works on and off e.g. succeeds 20 times then fails 5 then succeeds then fails etc …

When in a try/except it raises a KeyError exception.

When not in the try/except it raises a Too many requests error

Code

exchange_class = "Bitfinex"
....
exchange = eval('ccxt.%s ()' % exchange_class)
....
# In a loop that polls every 1 to 20 seconds
balances = exchange.fetch_balance()
