Pages 4.3 crashes on iMac Late 2013 Mavericks Pages 4.3 (latest update for iWork '09 afaik) constantly crashes (closes and shows "unexpectly quit" crash report) on a new iMac 27" (Late 2013) running 10.9 (.2) Mavericks
The crashes seem to be comepletely intermittent. Sometimes when writing, pasting text, dragging images.

Here are some crash reports:

The latest one:

This one happened after I completely reinstalled the machine (formatted the drive, installed mavericks over restore partition, created a new user, installed iwork from disc and installed 4.3 update and then dragged over my personal documents via a usb drive)

EDIT
I ended up updating to the new versions of pages since I couldn't get the bug to be fixed.
Slightly off topic, but with Mavericks installed, you can update to Pages 5.1 for no charge and maybe your problem will not occur.
