kubuntu feisty beta - installer chrashs on portition table

Maybe it's the same bug, I do not know: https://launchpad.net/ubuntu/+source/ubiquity/+bug/43125

I downloaded Kubuntu 7.04 beta, burned and booted. I was installing it. The installer asked about use the whole HD to install (automatic) or just a partition(manual). I chose manual and the partition table appeared. I marked /dev/sda3 for formatting. When I tried to edit it (intended to format from reiserfs to ext3) the installer chrashes and this error appears:
__________________________________________________

Traceback(most recent call last):

line 1942, in
on_partition_list_edit_activate
index=selected[0]
IndexError: list index out of range
__________________________________________________

I think the error says the same as me.

However I installed it sucessful. How? I edited the partition and after marked the checkbox of "Format?", then clicked next. I'm using Kubuntu now to post the bug :)

There is something else that I'm not sure if it's a bug. I connected to the internet and apt-get works. Konversation (IRC) too. But konqueror does not browse any site. I used apt-get to install Firefox and Mozilla worked!

It's an Asus F3JC laptop.

I have windows xp too.

Should I inform more information about hardware?

PS: My English it's not very fluent :(
