eric3 and qscintilla problem

[Petr Simon <debian@klubko.net>]

Hi,
I am just a Python noob and I get this when trying to run eric3:

Traceback (most recent call last):
 File "/usr/lib/python2.2/site-packages/eric3/eric3.py", line 130, in ?
   mw = UserInterface(loc, args)
 File "/usr/lib/python2.2/site-packages/UI/UserInterface.py", line 295, 
in __init__
 File "/usr/lib/python2.2/site-packages/ViewManager/__init__.py", line 
45, in factory
 File "<string>", line 1, in ?
 File "/usr/lib/python2.2/site-packages/ViewManager/Tabview.py", line

 File "/usr/lib/python2.2/site-packages/ViewManager/ViewManager.py", 
line 15, in ?
 File "/usr/lib/python2.2/site-packages/QScintilla/Editor.py", line 13, 
in ?
ImportError: cannot import name QextScintillaPrinter

What does it mean and what can I do about it?
Thanks Petr
