QNetworkAccessManager throwing qWarning() when internet connection is not available

Hi,
I am using the following code to download a webpage:

void CheckUpdates::checkUpdates()

{ connect(&manager, SIGNAL(finished(QNetworkReply*)), this, SLOT(fileDownloaded(QNetworkReply*))); connect(&timer, SIGNAL(timeout()), this, SLOT(killChecking())); QNetworkRequest request(QUrl("http://mywebsite.com/index.html")); manager.get(request); timer.start(10000); }

In case the PC does not have internet connection then the following message is thrown in qWarning:

QIODevice::seek: Cannot call seek on a sequential device
Category: default
File: io\qiodevice.cpp
Function: virtual bool QIODevice::seek(qint64)
Line: 634
Version: 1

I do not understand why qWarning() should be used for this purpose.
Can I disable QNetworkAccessManager or QNetworkRequest to not throw this error?
Or atleast make it to qDebug() instead?
The message is also not generic so that I could filter it out in my message handler.
Requesting some workarounds for this issue...
