break-word;">This is my attempt to fix the crash. As far as I followed the code, the \
crash is because of m_group == 0 in serverStateChanged() when the avahi server is \
initially &quot;registering&quot; or in &quot;collision&quot;, and not \
&quot;running&quot; 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 \
&quot;running&quot; state.

Additionally, the m_running variable was never reset to false in stop(), so the \
(sync) publish() would never return on failure.</pre>  </td>
