I had exactly this problem too with both gimp 2.2.9 and self compiled gimp 2.3.4.
I discovered that quitting klipper (the kde cut paste applet) fixes the problem - ie gimp no longer crashes on cutting large images. ii gimp 2.2.9-1 The GNU Image Manipulation Program ii klipper 3.4.3-3 clipboard utility for KDE -- Nick Craig-Wood <[EMAIL PROTECTED]> -- http://www.craig-wood.com/nick -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
