Test failures on Debian Unstable

[wRAR]

I ran the 2.3.0 test suite on the current Debian Unstable and got the following failures.

Two related to those CAMELLIA tests (Https11CustomCiphers.test_download and WebClientCustomCiphersSSLTestCase.testPayload):

<twisted.python.failure.Failure OpenSSL.SSL.Error: [('SSL routines', 'ssl3_read_bytes', 'tlsv1 alert internal error')]

Two related to the mitmproxy cert:

  File "/usr/lib/python3/dist-packages/mitmproxy/net/tls.py", line 369, in create_server_context
    context.use_certificate(cert.x509)
  File "/usr/lib/python3/dist-packages/OpenSSL/SSL.py", line 960, in use_certificate
    _raise_current_error()
  File "/usr/lib/python3/dist-packages/OpenSSL/_util.py", line 54, in exception_from_error_queue
    raise exception_type(errors)
OpenSSL.SSL.Error: [('SSL routines', 'SSL_CTX_use_certificate', 'ee key too small')]
