Comment 2 for bug 793679

I can confirm this bug.
I have copied from https://fedorahosted.org/system-config-printer/browser/ppdippstr.py and placed into /usr/share/kde4/apps/system-config-printer-kde/

then the output changes to:

kcmshell(6089)/kdecore (KSycoca) KSycocaPrivate::openDatabase: Trying to open ksycoca from "/var/tmp/kdecache-ingo/ksycoca4"

However, there is a lot of cupshelpers:
/usr/lib/python2.7/dist-packages/cupshelpers
/usr/lib/python2.7/dist-packages/cupshelpers/cupshelpers.pyc
/usr/lib/python2.7/dist-packages/cupshelpers/cupshelpers.py
/usr/lib/python2.6/dist-packages/cupshelpers
/usr/lib/python2.6/dist-packages/cupshelpers/cupshelpers.pyc
/usr/lib/python2.6/dist-packages/cupshelpers/cupshelpers.py
/usr/share/pyshared/cupshelpers
/usr/share/pyshared/cupshelpers/cupshelpers.py

smburi is also there, but in /usr/share/system-config-printer/

Yet, no success. Search path problem?
