Comment (by danielk):

 jya, I think the problem might be deeper than just changing how m_bonjour
 is deleted. I only looked at this a little bit but I think this might
 suffer from that QXXXSocket issue I discussed with you. i.e. where all the
 sockets are created in the same thread and all the socket handling ends up
 being done in that one thread. If so there are two workarounds: 1/ just
 pass a socket file descriptor instead of a QTcpSocket to the handler
 thread and create the QTcpSocket in the right thread or 2/ you can
 reassign the thread a QObject belongs to using http://qt-
 project.org/doc/qt-4.8/qobject.html#moveToThread.

 #1 has implications for Qt5 which changes the socket descriptor type from
 int to qintptr, but if you get it to work on Qt4.x I can easily make it
 Qt5 compatible since I have the build environment set up.

 Anyway, I only did a little of bit of debugging before deciding this was a
 rabbit hole I didn't have time for at the time. I did find that the way to
 reproduce this was to run bonjour in an environment where it could never
 start up properly (I don't remember the details.)
