Comment(by Mike Nix <mnix@…>):

 The bug shows up when mythsocketthread finds a socket in m_readyread_list
 that is ready to read when MythContext::d->eventSock is NULL.

 readyRead assumes d->eventSock is the socket to read.

 I can see three possible solutions:
 1: if (!d->eventSock) return;    // ie ignore the socket - probably bad
 2: have readyRead use the socket passed to it.
 3: make some code behave differently for sock != d->eventSock

 I don't know if m_readyread_list is intended to hold non-event sockets so
 I can't answer the question.
 The attached patch uses the socket passed to readyRead, and adds code to
 log what is happening for further diagnostics.
