In fact, this will crash the interpreter:

$ python -c "import PyKDE4.kdecore"

I've done some additional testing, including backing out my small patch in pyqt4 for Python 3. It still crashes. So I think the bug is elsewhere. The sip stuff hurts my brain, so I'm going to unassign myself from it, but I am happy to help others debug the issue.

I think this is RC for Alpha 2, so putting back the milestone and bumping importance.

Can somebody test if they need rebuilding?

I just updated to precise and I get a crash running the testcase given in comment #7:

$ python -c "import PyKDE4.kdecore"
python: /build/buildd/sip4-4.13.2/siplib/siplib.c:10938: sipEnumType_alloc: Assertion `(((currentType)->td_flags & 0x0007) == 0x0003)' failed.
Aborted (core dumped)

My python-kde4 is above the version said in comment #12:

$ apt-cache policy python-kde4
python-kde4:
  Installed: 4:4.8.2-0ubuntu1
  Candidate: 4:4.8.2-0ubuntu1

I was initially affected by frescobaldi crashing:

$ apt-cache policy frescobaldi
frescobaldi:
