Browser crashes when trying to draw Pie Chart using a js library (Something not implemented in qt?)

[Haso Keric]

Can someone verify a Qt Webkit bug - (no demo browser allowed, no arora) you will have to build your own little dummy browser using Qt Creator: launch http://www.jscharts.com/examples and open a Pie Graph - see if it crashes your application. - This is tested by me on Windows XP SP3 - Qt 4.5.1 - dynamic and static builds - clean source copies.

Tested on: ffox, ie, safari, arora = works!

Problem: when building my own browser = crash!

Tested on multiple pcs.

I have not tested it on other operating systems; but Windows XP by me is confirmed can someone else verify and assure i am not wrong..

Win Xp SP3

[20:12] <marcusU> vector_xyz: Does it kind of lock up that application when select the pie chart?
[20:12] <vector_xyz> yes
[20:12] <vector_xyz> it just locks it up
[20:12] <marcusU> It does for me, too.

I was told to do a backtrace by bdash and others in #webkit
first time doing it - idk if its any useful but i copied evertyhing i got when my Application froze
