[SailfishDevel] Bluetooth service discovery not working since 1.1.2.16

[Richard Rondu]

Hi Hannu,

I have fixed Qt Bluetooth like you described and it's working, a new rpm is
under way.

It's in my fork on github for those interested :
https://github.com/lainwir3d/qtconnectivity/commit/5f42edc7ce404db1a9fe95087bf6c0866df40771

Thanks again for the help !

Richard
