@Francis: You could try removing the QueuedConnection flag from here: shell/mainwindow.cpp: connect(Core::self()->documentController(), &IDocumentController::documentOpened, this, &MainWindow::updateTabColor, Qt::QueuedConnection); connect(Core::self()->documentController(), &IDocumentController::documentUrlChanged, this, &MainWindow::updateTabColor, Qt::QueuedConnection); Does it still crash then? Care to investigate a bit?
It crashes intermittently with those flags (or all the Qt::QueuedConnection flags around there) removed, but not every time as before. I'm a bit busy actually using KDevelop to poke inside it much, maybe later this week. Backtrace looks different again...

It seems to me as though Kate should crash the same way, but I can't make it do so. It does behave in a really unintuitive way that probably should be its own bug, but doesn't actually crash.
Hello everyone, I am a beginner in open source development and would like to contribute. I was wondering if I could contribute to this bug?
