It looks like it's necessary for the new libjpeg-progs to include a
conflict with libjpeg-turbo-progs, since at the moment APT tries to
install them in the wrong order. On my system at the moment:
wraith:/home/bjh21# dpkg -l 'libjpeg*progs'
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend

ii libjpeg-turbo- 1:1.3.1-3 i386 Programs for manipulating JPEG fi
Both libjpeg-progs 1:9a-2 and libjpeg-turbo-progs 1:1.3.1-6 are available
to APT, but it chooses to upgrade libjpeg-progs and keep back
libjpeg-turbo-progs:
wraith:/home/bjh21# apt-get dist-upgrade

APT needs to be told that the new libjpeg-progs can't coexist with
libjpeg-turbo-progs 1:1.3.1-3, which I think requires adding a Conflicts:
header to libjpeg-progs (or use of alternatives).
I've tried to re-organise this bug report to reflect the fact that changes
were needed to both packages. I've reassigned 764318 back to
libjpeg-progs alone, while there's a new clone to represent the (fixed)
lack of a Conflicts: header in libjpeg-turbo-progs. According to the BTS
documentation, it's only appropriate to have a bug assigned to two
packages if it can be fixed by a change to either one of those packages.
In this case, it appears that changes to both packages were required.
