Hello


After installing eric4 from source, I get this error:

-----------

The system is:
python 2.5.2
sip 4.7.2
Qt 4.4.0
PyQt 4.4.2
QScintilla 2.2
Eric4 4.1.5

All the package except QScintilla are installed from the debian 
repository (lenny)
QScintilla and the Python binding where rebuild from source

As additional info, I can add that some eric4 module (like the 
mini-editor or the preference dialog)
work if run stand alone

Any hint ?
The same error are generated from the lastest snapshot

Thanks
Gianluca
