Bug description:
  Nexus 4 running latest stable image -

  current build number: 25
  device name: mako
  channel: ubuntu-touch/stable/ubuntu
  last update: 2015-12-08 11:53:16
  version version: 25
  version ubuntu: 20151118.2
  version tag: OTA-8
  version device: 20150911
  version custom: 20151118.2

  I'm running the following command to capture a screenshot of a running
  app, the unity shell, the splash screen when apps load etc.

    adb shell mirscreencast -m /var/run/mir_socket  -n1

  I'm doing this in a script, across many hundreds of apps, so I'm doing
  it a lot. I'm seeing my script get wedged fairly often with errors
  such as this one:-

  [1449575031.562843] <ERROR> MirConnectionAPI: Caught exception at client library boundary (in release): /build/mir-AHj2eT/mir-0.17.1+15.04.20151105.1/src/client/rpc/stream_socket_transport.cpp(168): Throw in function virtual void mir::client::rpc::StreamSocketTransport::send_message(const std::vector<unsigned char>&, const std::vector<mir::Fd>&)
