<div style="margin: 8px 0; padding: 0 12px; color: #74777D;"><p style="padding: 0; margin: 8px;">What you're describing isn't really possible. Connections are disconnected when an object gets destroyed.</p>
<p style="padding: 0; margin: 8px;">How do I reproduce that crash?</p></div></div>
<div style="margin: 8px 0; padding: 0 12px;"><p style="padding: 0; margin: 8px;">That’s what puzzles me.</p>
<p style="padding: 0; margin: 8px;">It doesn’t always crash (only 5–10% of times closing Okular). If you add qDebug()s to the functions, you see the destructor beeing called before forgetButton() is called. (Assuming <tt style="background: #ebebeb; font-size: 13px;">~ToggleActionMenu() override</tt> is added.) Valgrind confirms that (just run <tt style="background: #ebebeb; font-size: 13px;">valgrind okular</tt> and close the window), and complains that forgetButton() is called on an already deleted object. (Invalid read of size 4 in QSet::isEmpty().)</p>
<p style="padding: 0; margin: 8px;">I hope that I misinterpret something.</p></div></div></div></div></div><br /><div><strong>REPOSITORY</strong><div><div>R223 Okular</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D21755">https://phabricator.kde.org/D21755</a></div></div><br /><div><strong>To: </strong>davidhurka, Okular<br /><strong>Cc: </strong>aacid, VDG, okular-devel, joaonetto, tfella, ngraham, darcyshen<br /></div>
