This started happening somewhere between August 21 and August 28: https://jenkins.qa.ubuntu.com/view/Saucy/view/AutoPkgTest/job/saucy-adt-apport/, presumably due to some Qt update.

The crash is trivially reproducible with

  python3 -c 'from PyKDE4.kdeui import KApplication; KApplication()'

https://launchpad.net/ubuntu/+source/pykde4/4:4.11.0-0ubuntu1 was uploaded around that time, but downgrading to https://launchpad.net/ubuntu/+source/pykde4/4:4.10.97-0ubuntu1 does not help.

What does help is to downgrade python3-pyqt4 and python3-sip to the previous versions:
  https://launchpad.net/ubuntu/+source/sip4/4.14.7-4ubuntu1
  https://launchpad.net/ubuntu/+source/python-qt4/4.10.2-2

affects: apport (Ubuntu) → python-kde4 (Ubuntu)

summary: - apport-kde crashed with SIGSEGV in QMetaObject::normalizedSignature()
+ KApplication now crashes immediately since last saucy sip and pyqt4
+ updates
