Webkit and Client Side Storage

Hello people.

I been having trouble getting the client side storage working with webkit.

Here is code i'm using can anyone see what i'm doing wrong?

Code:

---

QApplication::setApplicationName(TEXTAPPLICATION);
 
QApplication::setApplicationVersion(TEXTAPPVERSION);
 
QApplication::setOrganizationName(TEXTORG);
 
QApplication::setOrganizationDomain(TEXTORGDOMAIN);
 
QSettings settings; 
 
QWebSettings::enablePersistentStorage(TEXTDATAPATH);
 
QWebSettings::setOfflineStorageDefaultQuota(MAXQUOTA);
 
QWebSettings::setOfflineWebApplicationCacheQuota(MAXQUOTA);
 
QString url = "http://webkit.org/demos/sticky-notes/index.html";
 
ui->setupUi(this);
 
this->setWindowTitle(TEXTAPPLICATION); //set application windows title
 
ui->webView->settings()->globalSettings()->setAttribute(QWebSettings::DeveloperExtrasEnabled, true);
 
ui->webView->settings()->globalSettings()->setAttribute(QWebSettings::LocalContentCanAccessRemoteUrls, true);
 
ui->webView->settings()->globalSettings()->setAttribute(QWebSettings::LocalStorageEnabled, true);
 
ui->webView->settings()->globalSettings()->setAttribute(QWebSettings::OfflineStorageDatabaseEnabled, true);
 
ui->webView->setUrl(url);

I worked out that i'm getting this error in the inspector.

INVALID_STATE_ERR: DOM Exception 11: An attempt was made to use an object that is not, or is no longer, usable.

Seems to have something to do with window.openDatabase()

I'm having the same issue. I get that exact error in the inspector. I can't figure it out... Could it be a bug in Qt? Because it works just fine in Safari.

I know it's been a while since this question was posted.. I had the same issue and there is very little information about this error around web.
Indeed, error happens when calling openDatabase within JS and I managed to eliminate it with

Code:

---

QWebSettings::globalSettings()->setOfflineStoragePath("/some/writable/path/here");
