Linux beta 2.5.85, Qt 6.12.0: SIGSEGV when a Logitech G733 (046d:0ab5) USB receiver is removed. Stack: Battery::~Battery → QObject::~QObject → deleteChildren → libQt6DBus → QObject::objectName with null this. On connect, the log shows “Cannot create children for a parent that is in a different thread (Parent is QDBusTrayIcon)”. Possibly a tray icon thread-affinity bug. Seen once so far.
Since this has only happened once, could you let us know if it happens again or if removing other USB devices causes the same crash?
