Summary Shutdown problem after loading http://nzonlinemall.com/home.html

Reported 2011-05-26 02:30:25 PDT
Problem reported on the qt-webkit mailing list: I close the window after loading http://nzonlinemall.com/home.html , I can see the memory footprint starts to go up and I have to kill the process. Reproduced with QtWebKit on the QtWebKit 2.2 branch on Ubuntu 10.04 with Qt 4.7.1 and QtMobility 1.1.1. Some had difficulties reproducing the problem.

...Meant to actually put a comment with that attachment. Repro that's similar but not identical to what Laslo and Luiz report. Page begins loading, gets to 90% complete and UI goes unresponsive for ~30 seconds as CPU maxes and memory climbs. Ultimately it levels off at about 500 megs after 30 seconds and UI becomes responsive again. (Previous attachment shows this.) Window closes as expected when clicking to close after the UI becomes responsive again. Happens the same each time. Using Qt 4.8 Tech Preview (which I believe uses Webkit 2.2). MSVC2010 compiled from source on Win7. (I used fancybrowser, but see same behavior with browser demo or just headless code)

(In reply to comment #3) > Using Qt 4.8 Tech Preview (which I believe uses Webkit 2.2) <snip> Unfortunately not. Qt-4.8-tp1 includes QtWebKit-2.0. We're still working on the import (which is not trivial)

The same thing happens to Safari 5.0.5 on SnowLeopard.

We're having trouble finding a reduction and this bug is not always reproduceable. Removing from the release blockers by now as it's not that critical.
