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: http://pastebin.com/xTszDwNG (latest one, this one was when a image was dragged into pages) http://pastebin.com/k9NsMFpt http://pastebin.com/kYxh71np http://pastebin.com/TUMQctDL
The latest one: http://pastebin.com/g142aypG
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.
