[Bug or Feature Requests] aioredis connect raise 'Event callback failed'

[625781186]

env:
python 3.6.4 64bit
pyqt5 5.10.1
aioredis 1.1.0 ~1.3.0
quamash 0.6.1

error:

use asyncio loop is ok:

##testcode.py
from PyQt5.QtWidgets import QApplication, QProgressBar
from quamash import QEventLoop, QThreadExecutor

app = QApplication(sys.argv)
loop = QEventLoop(app)
asyncio.set_event_loop(loop)  # NEW must set the event loop

progress = QProgressBar()
progress.setRange(0, 99)
progress.show()

async def master():
    await first_50()


async def first_50():
    red_sql = await aioredis.create_redis_pool(f"redis://localhost:6379/1")

with loop: ## context manager calls .close() when loop completes, and releases all resources
    loop.run_until_complete(master())
