Public bug reported:
I often hook up my camera with a USB cable, and it's USB 1.1. I can
browse fine (including thumbnails), and I can copy files over with
useful speed ("full speed"). But whenever I start Ristretto on such a
file, I have to eventually kill it because it never comes back in time.
The access on the camera is on while Ristretto hangs, so presumably it
is doing something that causes it to reread the same information
unbuffered again and again or doing something else that is very, very
inefficient on a file system mounted via USB (reading bytewise and
adjusting the access time every time?).
Here is the camera description:

Here is the mount entry:
/dev/sdd1 on /media/dak/8867-BE11 type vfat
(rw,nosuid,nodev,relatime,uid=1000,gid=1000,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,showexec,utf8,flush,errors=remount-ro,uhelper=udisks2)
This is a reasonably straightforward amd64 Ubuntustudio installation.
All other basic utilities and operations on that "drive" provided by the
camera are reasonably fast and corresponding to what you can expect from
"full speed" USB 1.1.
But Ristretto is unusable. It needs to do something differently when
reading files: this just doesn't work. I've never seen fit to let it
complete but rather killed it after a few minutes.
