Udev doesn't mount usbkeys, sd cards

Binary package hint: udev

udev needs to be restarted after i start ubuntu karmic, otherwise, usb key, sd cards are not mounted.
the usbkey must be opened in the gnome file manager

i get this showing that udev receive events

nicolas@koala:~$ sudo udevadm monitor
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

KERNEL[1257081703.544596] add /devices/pci0000:00/0000:00:12.2/usb1/1-4/1-4:1.0/host4/target4:0:0/4:0:0:0/block/sdb/sdb1 (block)

sudo udevadm control --reload-rules

each time i start ubuntu karmic
after that, when i plug a usb key or sd card, the content of it is displayed correctly in the gnome file manager
