openoffice crashes the whole system

[h]

I've had this bug twice already ...

When pasting from a selection made on a website (typically, a 
confirmation page after ordering something online, because I have no 
printer, and I'm too lazy to try to print from popups), openoffice first 
hangs, then eventually X goes black and the whole system reboots and 
gets in to a background filesystem check after the boot ...

Here's my config:

- FreeBSD 6.2-STABLE FreeBSD 6.2-STABLE #0: Wed Aug 22 00:24:58 CEST 
2007 i386

openoffice.org-2.3.20070822

kde-3.5.7

768mb ram
1.5G swap

is this error known?
