[System Version]: deepin V25.1.0 [Preconditions]: Deepin 25.1.0, normal desktop session with dde-file-manager open. [Reproducibility Steps]: 1. Use the desktop normally with dde-file-manager open 2. Shut down the system [Expected Results]: System shuts down cleanly within a few seconds. [Actual Results]: dde-dconfig-daemon segfaults in libdtk6core.so on shutdown, causing dde-file-manager to enter a DBus retry loop trying to reconnect to the dead daemon. user@1000.service then times out after 2 full minutes before systemd force-kills it. Relevant journal entries: - kernel: dde-dconfig-daemon[941]: segfault in libdtk6core.so.6.7.34 - kernel: dde-shell[2534]: segfault in libdfm6-base.so - systemd[1]: user@1000.service: State 'stop-sigterm' timed out. Killing. - dbus-daemon: Activation via systemd failed for dde-dconfig-daemon.service: Refusing activation, D-Bus is shutting down. (repeated 7+ times)
