backtrace core (no debug symbols)

A couple of problems with the desktop notifications on Linux (Ubuntu 10.10), but the most important one is that the testbrowser crashes on some desktop notifications:

steps:

1. compiled from git QtWebKit 2.1 branch on gitorious
( ./Tools/Scripts/build-webkit --qt --release --file-reader --image-resizer --no-svg --no-javascript-debugger )
2. start the browser ./WebKitBuild/Release/bin/QtTestBrowser
3. open this url: http://www.beakkon.com/tutorial/html5/desktop-notification
4. click a couple of times on the two demo buttons ( NOTIFY / NOTIFY ME(HTML) )
5. sometimes it crashes after 1 or 2 clicks, sometimes it takes 20 clicks to crash it

result:
Segmentation fault

expected:
1. show html notifications (not just text)
2. no segmentation fault

environment:
Linux: Linux thijsterlouw-VirtualBox 2.6.35-22-generic #33-Ubuntu SMP Sun Sep 19 20:34:50 UTC 2010 i686 GNU/Linux
UA QtTestBrowser: Mozilla/5.0 (X11; U; Linux i686; en-US) AppleWebKit/534.3 (KHTML, like Gecko) QtTestBrowser/0.1 Safari/534.3
Qt: 4.7.3 (latest from qt.nokia.com)
QtWebKit: Latest git from 2.1 branch, with 2 patches (one patch from WebKit trunk to support Drag&Drop + one patch to fix build errors due to unexported symbols)
