Since KDE 4.3.3 (and perhaps 4.3.2) I can no longer mount my USB devices using graphical KDE interface. Three scenarios appends: 1) Dolphin shows the device icon in the place pane. But when clicking on it, nothing happen and .xsession-errors shows a lot of: -- virtual QVariant Solid::Backends::Hal::HalDevice::property(const QString&) const error: "org.freedesktop.DBus.Error.ServiceUnknown" , "" -- 2) Device notifier popup, but no icon in dolphin. .xsession-errors shows a bunch of: -- QStringList Solid::Backends::Hal::HalManager::findDeviceByDeviceInterface(const Solid::DeviceInterface::Type&) error: "org.freedesktop.DBus.Error.ServiceUnknown" virtual bool Solid::Backends::Hal::HalDevice::queryDeviceInterface(const Solid::DeviceInterface::Type&) const error: "org.freedesktop.DBus.Error.ServiceUnknown" -- 3) Nothing happen. I suspect a concern around Solid / Hal / D-Bus. However, I have tried to remove each configuration files (/etc/hal and /etc/dbus-1), remerged them, and rebooted. The problems still occur. Any hint? I'm surprised to see no other reports on this issue... Reproducible: Always Steps to Reproduce: 1. Plug USB device 2. Try to mount using KDE UI. Actual Results: No way to mount devices.

Another interesting error: $ solid-hardware list virtual QStringList Solid::Backends::Hal::HalManager::allDevices() error: "org.freedesktop.DBus.Error.ServiceUnknown" Sounds like a dbus service is not running...
Here are step to reproduce this bug: 1. restart hald (X restarts too) with an usb stick plugged in (not mounted), 2. hal-device is working (it is listing some stuff) 3. using kde4 device notifier, mount the usb stick 4. the usb stick is mount but do not appear in locations of dolphin 5. hal-device no longer works (Could not initialise connection to hald. Normally this means the HAL daemon (hald) is not running or not ready.) Current kde version: 4.4.0 (also present with 4.3.X) I started hald with verbosity, here are the messages when mounting via kde4: Feb 13 19:41:44 banquise hald[4785]: 19:41:44.714 [I] hald_dbus.c:5198: OK for method 'Mount' with signature 'ssas' on interface 'org.freedesktop.Hal.Device.Volume' for UDI '/org/freedesktop/Hal/devices/volume_uuid_0D5A_4ED4' and execpath 'hal-storage-mount' Feb 13 19:41:44 banquise hald[4785]: 19:41:44.714 [I] hald_dbus.c:4082: no need to enqueue Feb 13 19:41:44 banquise hald[4785]: 19:41:44.754 [I] osspec.c:298: /proc/mounts tells, that the mount has tree changed Feb 13 19:41:44 banquise hald: mounted /dev/sdd1 on behalf of uid 1000 Feb 13 19:41:44 banquise hald[4785]: 19:41:44.756 [I] hald_runner.c:110: runner_server_message_handler: destination=(null) obj_path=/org/freedesktop/DBus/Local interface=org.freedesktop.DBus.Local method=Disconnected Feb 13 19:41:44 banquise hald[4785]: 19:41:44.756 [I] hald_runner.c:151: runner process disconnected Feb 13 19:41:44 banquise hald[4785]: 19:41:44.756 [I] device.c:1894: Removing locks from ':1.38' It seems that after this operation, the dbus service associated with hald stops working. Any hints?
