<p>My thinking was the following:</p>

<ul class="remarkup-list">
<li class="remarkup-list-item">Guard code execution in <tt style="background: #ebebeb; font-size: 13px;">StatusNotifierItemSource::activate</tt> against deleted <tt style="background: #ebebeb; font-size: 13px;">m_statusNotifierItemInterface</tt> by comparing it to the old pointer value</li>
<li class="remarkup-list-item">In case not deleted emit a callback signal, which is received in <tt style="background: #ebebeb; font-size: 13px;">StatusNotifierItemJob::activateCallback</tt>, if job object hasn't been deleted before</li>
<li class="remarkup-list-item">set the result, which is received by <tt style="background: #ebebeb; font-size: 13px;">StatusNotifierItem.qml</tt> as long as it exists. I mean since it connects to the finished signal of the job, there shouldn't be a problem, if it got deleted earlier.</li>
