[Qt 5.11] Sql Query from QThread

Migrating to 5.11 version (from Arch Linux repository) caused a regression in my application.

I have a main thread (the QMainWindow), which establishes a connection to a sqlite database, the class SqlQueries, a collection of static functions, and a QThread class, used to export data to a file.

Previously to 5.11 I was able to call a SqlQueries static method from the QThread class.

After upgrading to 5.11 calling a  query from the thread class I got the following error:

QSqlDatabasePrivate::database: requested database does not belong to the calling thread.
QSqlQuery::prepare: database not open
static QString SqlQueries::getName(const int&) ERROR:  ""  :  QSqlError("", "Driver not loaded", "Driver not loaded")

Downgrading to 5.10.1 solves the problem.

Is this a bug or anything changed in API?

Thanks
