[Interest] qt5 settings ini format regression

[Frank Hemer]

In QT5, QSettings with IniFormat being used with keys like 'general/entry1' do 
write all items into a '%General' section.
This is what the doc explains as a way to ensure no keys without a group may 
get overwritten.

Unfortunately it seems that with qt5 there appear multiple '%General' sections 
when accessed as described above.
This is a regression to the 4.x.

Can anybody confirm this behavior, maybe with other os (I tried linux) - I'll 
file a  bugreport then.

Thx
Frank
