I already know that backtrace is not very usefull.
The packages containing debug information for the following application and libraries are missing:

/usr/bin/python3.2mu
/usr/lib/python3/dist-packages/PyQt4/QtGui.cpython-32mu.so
/usr/lib/python3/dist-packages/sip.cpython-32mu.so

Do you know what can I do to get a better backtrace?

** Tags added: apport-kde kubuntu

** Description changed:

  ubuntu-bug command makes apport-kde to crash if it is invoked with a package name which does not exist as argument.
  Steps to reproduce:
  1) Open a terminal.
  2) Run this command: ubuntu-bug blablabla
  3) You will see a dialog with the information about "blablabla" package does not exist.
- 4) After closing the dialog, apport crash, and KDE Crash Handler intercepst it.
+ 4) After closing the dialog, apport crashes, and KDE Crash Handler intercepst it.
  
  Backtrace:
  
  Application: Apport KDE (python3.2mu), signal: Segmentation fault
