Subject
QWebSettings::OfflineWebApplicationCacheEnabled doesn't work

Steps to reproduce / test case
Create a simple QWebView.
Call
QWebSettings::globalSettings()->setAttribute(QWebSettings::OfflineWebApplicationCacheEnabled,
true); which should be the default anyway.
Call QWebSettings::setOfflineStorageDefaultQuota(10 * 1024 * 1024);

I also tried different settings for OfflineStoragePath.

Try a page using offline application cache, like
http://webkit.org/demos/calendar/Calendar.html.
There should be a file called ApplicationCache.db somewhere containing the
cached files. But there is no such file.
Refreshing the page mentioned above needs online access to work. This should
not be the case.

More information
I found qt_websettings_setOfflineWebApplicationCachePath() to be a free
function in qwebsettings.cpp, so I tried to call it and test what might happen.
Setting the path using the mentioned function enables the web application
cache, an ApplicationCache.db is created in the provides path.
But it seems like the feature is somewhat broken. Restarting the test
application with an already created ApplicationCache.db frequently crashes the
application. Also, it seem as if the caching doesn't work altogether.
