Application jammed when doing host lookup with IPv6 access point

Steps to reproduce:
1. Make sure you have packet data IAP defined ( Something like in Shot(03).png) and 'Network type' = IPv6 as shown in Shot(04).png.
2. Make sure the above defined IAP has highest priority and access point is automatically used, or make sure that the above defined IAP is selected when program is executed in step 3
3. Launch attached program and click 'Resolve Host' button. -> Application gets jammed and do not respond to any events. Application cannot be closed without rebooting the device

Native web browser gives error: "No packet data connection available", but Qt application freezes.
