Package: scratch
Version: 1.4.0.6~dfsg1-5
To reproduce: Start scratch. Select Scene and the Backgrounds tab, click
the Import button.
A file selector appears, with thumbnails of available backgrounds.
Select Indoors --> kitchen (corresponding file is
/usr/share/scratch/Media/Backgrounds/Indoors/kitchen.jpg).
The image isn't loaded correctly, just a blank box instead of a
thumbnail in the list of backgrounds (unlike the file selector which did
show a correct thumbnail), and selecting the background has no effect,
the scratch scene just stays blank. There are no error messages as far
as I can find.
This is in contrast to loading Indoors --> bedroom1
(/usr/share/scratch/Media/Backgrounds/Indoors/bedroom1.gif, a gif rather
than a jpeg), which works fine. Which makes me think it's a problem with
the jpeg support.
The squeak wm appears to link with libjpeg.so.62:

squeak-wm is version 1:4.10.2.2614-4.1, and libjpeg is package
libjpeg62-turbo, version 1:1.5.2-2. I'm running on a debian gnu/linux
x86_64, upgraded to stretch. For completeness, kernel 4.9.0-4-amd64,
libc6 version 2.24-14.
(But I think this is an old problem, I had the same experience last time
I tried scratch, a few years ago, but it seems I unfortunately didn't
bug report it properly at the time).
