From Debian bug report http://bugs.debian.org/203755

I have a wacom tablet with the following devices: stylus, eraser, pointer 
+ the core pointer which is the normal mouse. It is a Graphire2, usb.

The "Devices" window (File -> Dialogs -> Device status...) does not display
the active device. I've a black arrow in front of 'core pointer' and it does
not move when I change the device used. 

One the same window, the button "Configure input devices" does nothing.

The box with the tools options (File -> Dialogs -> Tools Options) gives the
informations for the correct, currently in use, device.

If I want to pickup a new tool for the stylus, the eraser or the pointer, I
can't: the active device becomes the one marked with the black arrow (the
core pointer). 

The active device is the correct one only when I'm on the drawing area.
