contains the test.html, 5MB download.txt and webkit crash call stack

Qt Anomaly browser crashes while downloading a 5MB file through AJAX.

Preonditions:
flash the Vasco with latest 9.2 platform release. Install the Qt Anomaly browser.
Make sure that a valid access point is available.

Unzip the attachment.
Host the 5MB txt file(download.txt) in the local http server(e.g. Apache).
Host the test.html file in the same server.

Steps: 
1/ Run the Anomaly browser and open the test.html hosted in the server
2/ Enter the url for the download.txt hosted in the text box
3/ click on the button to download

Expected Result: Should download successfully

Actual result: Crash occurs after it download around 3-4 MBs

Note: If the crash is not observer in the first attemp, click the button again once the download is complete.
Crash will be observed in couple of attempts. Also if the network is slow, increase the time out period in the test.html.

Webkit crash call stack is attached.

webkit crash in Qt Test Browser

[Ganesh]

The crash is reproducible using the attached "XHRDownload.html" file in "Qt Test Browser" in the latest Vasco 9.2 platform build.
So reopening the bug and attaching the XHRDownload.html.
Steps remains the same except XHRDownload.html should be used instead test.html attached previously.

Fix required for Qtwebkit 2.2

Please follow http://trac.webkit.org/wiki/QtWebKitBugs when reporing bug here (keywork Qt was missing so the bug was not tracked).

Could you include a backtrace of the crash?

If this is supposed to be speed test like the one in 46746 then this can be fixed with not trying to assign the data to <p> .

Current setup in Symbian we can assign ~1MB of text to single div, not more.
It doesn't need any downloading... just make a HTML page with more than 1MB of text in single <p> and it crashes in QtWebkit2.1.
