Comment # 14 on bug 841250 from Bernhard Wiedemann

found that openSUSE:Factory/yast2-slide-show still has in
yast2-slide-show-3.1.12/SuSELinux/slideshow.xml
<!ENTITY suse-version "12.3">

which is rendered into the slides via the &suse-version; entity

this differs from what is in https://github.com/yast/yast-slide-show master
