>Description:
	With libgphoto2-2.4.13, any attempt to enumerate all images from
	a Canon camera (e.g. "gphoto2 -L", but also occurs with GUI frontends
	such as Digikam) enters an infinite recursion, and ultimately causes
	a crash due to stack exhaustion.
>How-To-Repeat:
	Connect Canon camera. Execute "gphoto2 -L".
>Fix:

	This was fixed upstream:
	http://gphoto.svn.sourceforge.net/viewvc/gphoto/trunk/libgphoto2/libgphoto2/gphoto2-filesys.c?revision=13932&view=markup

	so the solution is to either include this patch in the port, or simply
	upgrade the port to upstream release 2.4.14.
