Description:
When I try to import Photos of my Casio Exilim Cam with F-Spot or gnome-
volume-manager-gthumb, it always tells me, no camera detected. When I
run it form the terminal, I get the following Error:

20096: arguments to dbus_message_new_method_call() were incorrect, assertion "_dbus_check_is_valid_path (path)" failed in file dbus-message.c line 797.
This is normally a bug in some application using the D-BUS library.
libhal.c 995 : Couldn't allocate D-BUS message
error: libhal_device_get_property_type: (null): (null)

HAL version: 0.5.7-1ubuntu1 
DBUS version: 0.60-2ubuntu14
