Verbosity level > 2 crashes daemon

Daemon crashes with verbosity level > 2.

Confirmed error somewhere in daemon.cpp lines 383 - 400:

if (verbose > 2) {
    bool ok = ads1115_p->setLowThreshold(0b0000000000000000);
    ok = ok && ads1115_p->setHighThreshold(-32768);
    if (ok)
        qDebug() << "successfully setting threshold registers";
    else
        qWarning() << "error: failed setting threshold registers";
    qDebug() << "single ended channels:";
