I can confirm this but it's probably a pykde bug. *** Bug 189896 has been marked as a duplicate of this bug. *** *** Bug 200135 has been marked as a duplicate of this bug. *** Still in Kubuntu JJ with added KDE4.3
Also added bugs.launchpad.net #171572 for current KK version
Uppdated trace from Kubuntu JJ with recompiled python-qt4 source to make sure it matches.
Application: Miniprogram for skrivare (printer-applet), signal: Segmentation fault
