Android service is crashing when GPS is initialized

Hi,

When I try to initialize GPS with
QGeoPositionInfoSource::createDefaultSource(this);
Service is crashing then it is restarted and crashing again.
I have prepared example:
https://github.com/frankipl/service-test-gps

In adb logcat there is:
D/libservice.so(20818): ../../service-test-gps/service-service/gps.cpp:7 (bool Gps::initGps()): qwerty Gps::initGps before source
D/hawaii.hwcomposer( 1452): FBDevice::vsync called 60 times
