Bug 167597

Description of problem: I have a Canon SD500 (Ixus 700) that I
always used with gphoto without problems. But now, I am getting 
a "Corrupted data" error, and gphoto does not work anymore (FC4 
fully updated with both gphoto2-2.1.6-1 and testing gphoto2-2.1.6-1
RPM's). I cannot access the Camera card, independently of its 
content (even when empty).

Perhaps this bug is related to some of these:
