That seems OK to me.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">I only see two possible reasons why m_screenConfiguration could still end up being 0.</p>

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Some other class calls load() without calling setShell. Put a breakpoint in load to figure out who does that.</p>

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">The "m_screenConfiguration = qobject_cast<KScreen::GetConfigOperation*>(op)->config();" (in the setShell method) somehow fails and returns a null pointer.</p>
