crash is because of m_group == 0 in serverStateChanged() when the avahi server is \
initially "registering" or in "collision", and not \
"running" yet. When e.g. KTorrent starts, it is possible that the avahi \
server needs some time until it is fully setup. The m_group is initialized when the \
first tryApply() is called, which only happens when server is initially in \
"running" state.
Additionally, the m_running variable was never reset to false in stop(), so the \
(sync) publish() would never return on failure.</pre> </td>
