Public bug reported:
Binary package hint: gnome-utils
On my system, a fully updated Edgy Eft, 2.6.17-11-generic kernel on an
Asus M2N-SLI with AMD X2 4600+ 65W processor, 2GB RAM, I intermittently
get segmentation faults when taking screenshots (gnome-screenshot, from
command-line or from print screen button.) The contents of the Bug
Buddy window are as follows:

This happens about 3 of every 5-10 calls to gnome-screenshot.
Additionally, I regularly have problems writing PNG files from *any*
application. Segmentation faults that result from the other
applications are at exactly the same place as the one listed above.
I've performed memtest86+ for three cycles with no errors detected.
I have tested this with a Live Edgy CD with the same results. I have
also tested this with Feisty Herd 5 with the same results. I am in the
process of testing this on Dapper (as soon as the torrent finishes.) I
will be happy to provide any further information as required - this is a
big show-stopper for me.
