Using the following code:

from mitmproxy import proxy, options
from mitmproxy.tools.dump import DumpMaster
from mitmproxy.addons import core




opts = options.Options(listen_host='127.0.0.1', listen_port=8081)
pconf = proxy.config.ProxyConfig(opts)

m = DumpMaster(None)
m.server = proxy.server.ProxyServer(pconf)
#print(m.addons)
print(m.addons)
#m.addons.add(core.Core())

try:
    m.run()
except KeyboardInterrupt:
    m.shutdown()

When running the above the following error is thrown:

mitmproxy has crashed!
Please lodge a bug report at: https://github.com/mitmproxy/mitmproxy
127.0.0.1:48110: clientdisconnect

According to the following a simple m.addons.add(core.Core()) should fix this however as can be seen in the addon list Core is already loaded:

'<mitmproxy.addons.core.Core object at 0x7f1521916e48>',

Any suggestions would be welcome, it seems to be a similar issue as posted here:

System information

python version: Python 3.6.5
