Undefined reference to when using QtMobility in simulator

[ScienziatoBestia]

Hi,
I'm trying to compile a simple application that uses the QGeoAddress class.
I put these lines to the project file:

symbian:TARGET.CAPABILITY += NetworkServices, location

# If your application uses the Qt Mobility libraries, uncomment
# the following lines and add the respective components to the 
# MOBILITY variable. 
CONFIG += mobility
MOBILITY += Location

but I obtain the error
.../destination.h:13: error: undefined reference to `QtMobility::QGeoAddress::~QGeoAddress()'

I use Ubuntu and I have the last QT SDK installed (with QTMobility 1.2)
I'm trying to compile for simulator.
Can someone help me? What is wrong?

Thanks to all.
I found the problem:
MOBILITY += location and not
MOBILITY += Location

thanks, bye
