Did you visit the printer settings page? Are there any other System Settings modules installed that use the Python language?
If you can provide the information requested in comment #1, please add it. If the crash is caused by visiting the printer settings page, it would be a duplicate of bug 283611.

Created attachment 64976 [details] New crash information added by DrKonqi systemsettings (1.0) on KDE Platform 4.7.2 (4.7.2) using Qt 4.7.4 - What I was doing when the application crashed: I had just asked the printer to print a test page. I previously had crashes when deleting a printer and when adding a printer. -- Backtrace (Reduced): #6 0x00007f9e4cdce0f5 in QHash<void*, PyQtProxy*>::duplicateNode(QHashData::Node*, void*) () from /usr/lib/python2.7/dist-packages/PyQt4/QtCore.so #7 0x00007f9e6206c637 in QHashData::detach_helper2 (this=0x205f050, node_duplicate=0x7f9e4cdce0f0 <QHash<void*, PyQtProxy*>::duplicateNode(QHashData::Node*, void*)>, node_delete=0x7f9e4cdce0e0 <QHash<void*, PyQtProxy*>::deleteNode2(QHashData::Node*)>, nodeSize=<optimized out>, nodeAlign=8) at tools/qhash.cpp:235 #8 0x00007f9e4cdd2ca7 in sipQtFindSipslot () from /usr/lib/python2.7/dist-packages/PyQt4/QtCore.so #9 0x00007f9e4ca4571e in sipWrapper_traverse (arg=0x0, visit=0x7f9e4dc8b620 <visit_decref>, self=0x2167170) at /build/buildd/sip4-4.12.4/siplib/siplib.c:9648 #10 sipWrapper_traverse (self=0x2167170, visit=0x7f9e4dc8b620 <visit_decref>, arg=0x0) at /build/buildd/sip4-4.12.4/siplib/siplib.c:9629
I am not really sure anymore, but it is possible that I may have tried to add a new network printer to the system. I had to get my system back up and running in working order so, I just went and did a complete new install of my dual boot system. Did not want to get stuck with only windows. The new install did not take very long since I do routine backups of certain folders.
