service meta data file is not getting exported to correct location through QTSERVICE.DESCRIPTOR

We are facing a problem with QTSERVICE.DESCRIPTOR macro. In our .pro file we use following commands to register our service meta data xml file with QT service framework database:

CONFIG += plugin mobility qtservice
PLUGIN_TYPE = serviceframework
MOBILITY = serviceframework
QTSERVICE.DESCRIPTOR = nokiaurihandlerplugin.xml

Problem is that the xml file is getting exported to:
t:/epoc32/data/T/epoc32/winscw/c/private/2002AC7F/des/nokiaurihandlerplugin.xml

and t:/epoc32/data/T/epoc32/data/z/private/2002AC7F/des/nokiaurihandlerplugin.xml

instead of:
t:/epoc32/winscw/c/private/2002AC7F/des/nokiaurihandlerplugin.xml

and t:/epoc32/data/z/private/2002AC7F/des/nokiaurihandlerplugin.xml

So the problem is clear that either QTSERVICE.DESCRIPTOR macro or something in QT service framework is out of whack.
Because of this issue the services are not getting registered with QT service framework database and hence they can't be loaded from any application.
This issue is present from wk 11 mcl onwards till date. Wk 10 mcl doesn't have this problem.
I tried to import our service meta data xml file explicitly as follows:

addFiles2.sources = nokiaurihandlerplugin.xml
addFiles2.path = /private/2002AC7F/des

DEPLOYMENT += addFiles addFiles1 addFiles2 xmlautoimport installer

So the service meta data xml file gets exported to appropriate location but still it doesn't get registered with the QT service framework database.
