Did you read this blog: https://blogs.kde.org/node/3919
You somehow have to notice the the dialog gets deleted during exec(). This is only possible with a QPointer. After exec() when you want to access the pointer, you've to check if the QPointer is null before accesing them:</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">QPointer<KNS3::DownloadDialog> dialog(new KNS3::DownloadDialog(q));
dialog->exec();
if (dialog)
{
dialog->getValues();
}
delete dialog;</p></pre>

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">So, if I get this right (also the content of the page you linked to) your critisism is not against the ScopedPointer itself but against how I used it.
Because QScopedPointer also has the bool overload and can be used in if conditions.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">QScopedPointer<KNS3::DownloadDialog> dialog(new KNS3::DownloadDialog(q));
dialog->exec();
if (dialog && !dialog->changedEntries().isEmpty())
{
m_provider->rediscoverThemes();
fillList();
}</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Seems to be alright?</p></pre>

QScopedPointer is <em style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;">not</em> reset when dialog is deleted inside exec(). So the only way is to use QPointer + delete.</p></pre>

So I tested it with two crashy dialogs in libkdegames.
Please comment in case I forgot to think about something.</p></pre>
