For some months I had not worked on Symbian. I wanted to upgrade to the latest versions. Qt 4.6 and Qt-Mobility 1.0.0 worked fine. I see now the upgrade caused the problem.
Thanks

At first glance there is nothing out of the ordinary in your code. The only point I could make is related to the Qt version. Mobility 1.0.2 was based on Qt 4.6.3. Mobility 1.0.2 doesn't even compile with Qt 4.7 as 4.7 moved on after the 1.0.2 release.
It is unlikely that we are going to redistribute Mobility 1.0 using Qt 4.7. The preferred way going forward is to use Mobility 1.1 once you make the shift to 4.7.
The official combinations are:
Mobility 1.0.x -> using Qt 4.6.3
Mobility 1.1 -> using Qt 4.7 (about to be released)

Are you saying that it doesn't even work using Qt 4.6.3?

P.S. There is a small chance for a null pointer crash in your application. QGeoPositionInfoSource::createDefaultSource(parent) may return a null pointer in some cases.
