For me in edgy, this is caused by an old installation of istanbul, where the .pyc and .pyo files was not removed correctly. The .py files was gone...
I did the following sudo apt-get remove --purge istanbul found that I still had files under /usr/lib/python2.4/site-packages/istanbul/ with extensions .pyc and .pyo. sudo rm -rf /usr/lib/python2.4/site-packages/istanbul/ sudo apt-get install istanbul Now it works...
