Hasn't happened since August, i guess we fixed it somehow. I'll set it to incomplete and let it autoexpire. ** Changed in: unity8 (Ubuntu) Status: New => Incomplete ** Changed in: qtmir Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1489072 Title: /usr/bin/unity8:11:LauncherModel::applicationRemoved:LauncherModel::qt_static_metacall:QMetaObject::activate:QMetaObject::activate:QAbstractItemModel::rowsAboutToBeRemoved To manage notifications about this bug go to: https://bugs.launchpad.net/qtmir/+bug/1489072/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

After digging for a while in QtMir's code, the code path described by the stacktrace seems ok too. One notable thing: according to errors.ubuntu.com the issue started happening first on 4th of August, which is when a refactoring of the code in question landed in qtmir. Could not manually reproduce the issue yet. The stack trace says it happens when an application is closed by the user, or at least a ApplicationManager.stopApplication() call is issued from qml. That could also be when shutting down the phone and closeAllApps() is called. ** Changed in: unity8 (Ubuntu) Status: Invalid = New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1489072 Title: /usr/bin/unity8:11:LauncherModel::applicationRemoved:LauncherModel::qt_static_metacall:QMetaObject::activate:QMetaObject::activate:QAbstractItemModel::rowsAboutToBeRemoved To manage notifications about this bug go to: https://bugs.launchpad.net/qtmir/+bug/1489072/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

LauncherModel::applicationRemoved() is connected to ApplicationManager::rowsAboutToBeRemoved(). The line that crashes is applicationManager-get(index)-appId(). Apparently get() returns a nullptr. However, in rowsAboutToBeRemoved() items should still be valid so connected parties can handle it. Reassigning to QtMir. ** Also affects: qtmir Importance: Undecided Status: New ** Changed in: unity8 (Ubuntu) Status: New = Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1489072 Title: /usr/bin/unity8:11:LauncherModel::applicationRemoved:LauncherModel::qt_static_metacall:QMetaObject::activate:QMetaObject::activate:QAbstractItemModel::rowsAboutToBeRemoved To manage notifications about this bug go to: https://bugs.launchpad.net/qtmir/+bug/1489072/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
