Bug Description

Using scratch on ubuntu 13, jpeg images fail to load, either in the thumbnail view or as "stages" or "sprites"

I ran strace, and it looks like a plugin hasn't been bundled:

[pid 7317] open("/home/user/somefile.jpg", O_RDONLY) = 5

[pid 7317] open("/lib/x86_64-linux-gnu/JPEGReadWriter2Plugin", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
[pid 7317] open("/usr/lib/x86_64-linux-gnu/JPEGReadWriter2Plugin", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
[pid 7317] open("/lib/JPEGReadWriter2Plugin", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
[pid 7317] open("/usr/lib/JPEGReadWriter2Plugin", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
[pid 7317] munmap(0x7f2a793f9000, 88132) = 0
[pid 7317] open("/usr/lib/scratch/plugins//so.JPEGReadWriter2Plugin", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
[pid 7317] stat("/usr/lib/scratch/plugins//so.JPEGReadWriter2Plugin", 0x7fff4d9bf560) = -1 ENOENT (No such file or directory)
[pid 7317] open("/usr/lib/squeak/4.10.2-2614//so.JPEGReadWriter2Plugin", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
[pid 7317] stat("/usr/lib/squeak/4.10.2-2614//so.JPEGReadWriter2Plugin", 0x7fff4d9bf560) = -1 ENOENT (No such file or directory)
[pid 7317] open("/lib/x86_64-linux-gnu/libJPEGReadWriter2Plugin.so", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
[pid 7317] open("/usr/lib/x86_64-linux-gnu/libJPEGReadWriter2Plugin.so", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
[pid 7317] open("/lib/libJPEGReadWriter2Plugin.so", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
[pid 7317] open("/usr/lib/libJPEGReadWriter2Plugin.so", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
[pid 7317] munmap(0x7f2a793f9000, 88132) = 0
[pid 7317] close(5) = 0

so we can see that the plugin failed to load, and that the jpeg file wasn't read.

looking in the /usr/lib/squeak/plugins/4.10.2-2614 and /usr/lib/scratch/plugins directory, this plugin isn't listed.

please could the packaging be updated.

my daughter thanks you!

This bug could be related to Debian bug 744289 - according to comments at Debbug 744289 this problem can be easily fixed:

Me and Tim discussed this, and I've found a fix. The issue is due tothe Debian package inheriting a patch from the original Debian packager making it link against the system libjpeg (rather than libjpeg bundled in the squeak-vm sources). For some reason, it seems squeak-vm isn't happy working with the newer libjpeg, so I've removed that patch and it all seems well.
I'll post here when the updated squeak-vm is added to the PI repository, which should be tomorrow, see http://www.raspberrypi.org/forums/viewtopic.php?f=77&t=15583&start=25
