Can the developer of this webkit check whether cookies do not work ?
Here an example URL to reproduce, it is an RPN and expression javascript scientific calculator which saves its data (RPN stack and numbers) as a cookie, so a reload of the page retains the numbers on the stack which is similar to the good old 'permanent memory' calculators.

This works in ANY browser, even on Nokia phone mobile browsers, except this webkit engine where it always starts with 0, so it is easy to reproduce.
