Hi, I've applied this workaround (my /etc/dbus-1/system.d/hal.conf attached).
What happens is this: I Plug in my USB-stick. I open Konqueror and go to the location: "media:/" Now, I click on the symbol of my USB-stick ("256MB removable drive"). Immediately, a popup-window opens and I still get the "unknown error". When I open a Konsole and type in: >>pmount-hal /dev/sda1<<, the USB-stick is successfully mounted under /dev/usbdisk (is this the expected behavior or should it be on another location?). Unmounting via right-click in Konqueror ("Safely remove") or >>pumount /dev/sda1<< works. When I enter into the Konsole: >>kio_media_mounthelper -m "media:/dev/sda1"<<, I get the same "An unknown error has occurred" as when klicking on the media symbol in Konqueror. **** Additionally, when I klick on "removable media" (Speichermedien) in KDEs control bar (Kontrolleiste), a Konqueror window opens with the location "/media" opened instead of "media:/", and as a result, there is no folder or icon to mount/unmount the USB-stick.
