Reproduced. Steps to Reproduce: 1. Connect to a host that is down. 2. Press Disconnect. 3. Repeat 1 and 2 several times. 4. After a while, something happens and KRDC crashes. Git commit ba6baad9b49a8a7fe57f27046631fc00c177e1a0 by Lamarque V. Souza. Committed on 12/03/2021 at 15:26. Pushed by lvsouza into branch 'fix_crash_on_disconnect'. Fix crash when closing a tab. TabbedViewWidget::removePage is called twice for the same page, which leads to crash on the second run. It is called by those two signals in mainwindow.cpp: connect(disconnectAction, SIGNAL(triggered()), SLOT(disconnectHost())); connect(view, SIGNAL(disconnected()), this, SLOT(disconnectHost())); M +3 -0 tabbedviewwidget.cpp https://invent.kde.org/network/krdc/commit/ba6baad9b49a8a7fe57f27046631fc00c177e1a0 |
