<p>in part.cpp, this micht change the part/child relationships and get yourself of this problem. can you give it a quick try?</p></blockquote>
<p>Seems like sidebar becomes a (grand-)child of Shells QTabWidget, no matter what you set as parent widget in Sidebar Ctor. This is because of <tt style="background: #ebebeb; font-size: 13px;">setWidget( m_sidebar )</tt> in Part::Part(), and <tt style="background: #ebebeb; font-size: 13px;">m_tabWidget->addTab( firstPart->widget(), QString() )</tt> in Shell::Shell(). Then C++ Dtor order lets Shell::~Shell (cleans up child widgets, including sidebar) be called earlier than Part::~Part.</p>

<p>Would it be an option to save sidebar state in <tt style="background: #ebebeb; font-size: 13px;">Part::closeUrl()</tt>?<br />
It is called early enough by Shell Dtor. For me it fixes the segfault, and "closeUrl" sounds like a reasonable action to cause document related state saving.</p></div>

<p>The thing is that whether you have the panel open or not is not really document related.</p>
<p>I think what we should do is just save the option when it changes, like we do in Part::slotShowLeftPanel and Part::slotShowBottomBar</p></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/D11051">https://phabricator.kde.org/D11051</a></div></div><br /><div><strong>To: </strong>dileepsankhla, Okular, aacid<br /><strong>Cc: </strong>tobiasdeiminger, aacid, sander, Okular, michaelweghorn, ngraham<br /></div>
