I have installed Dropn900 today and it doesn't start.

I have the "pyQt4 Full Install" and when i try to start the dropn900 via console i'll get
"File "./dropn900.py", line 7, in <module> from PyQt4.QtGui import QApplication
RuntimeError: the sip module implements APO v8.0 but the PyQt4.QtGui module requires API v7.1"

Any hints for an solution to get it fixxed ?

Edit:
sudo apt-get install python2.5-sip4=4.10.5-maemo0

also worked for me - thanks!
