Qt Bearer api crash

Hi,

I have few crashes once I have started to port from cp sfw to qt sfw.
Accessing the following mobility api's N97.

The source code compiles fine. But when installed on device it crashes.
The sources is

iSession = new QtMobility::QNetworkSession(aConfig, this);
iSession->error()
iSession->errorString()

And also when the connection is closed, our component crashes.

It is crashing in the bearercloud example.

void Cloud::newConfigurationActivated()
{
IN;
QString bearerName = configuration.bearerName();
LOGTXT("1");
if (!svgCache.contains(bearerName))

{ LOGTXT("2"); if (bearerName == QLatin1String("WLAN")) .... }

When there is access to the bearer name.
