Starts ok for me in Win7 and OSX 10.6, under QT, with pyside 1.1.0-2.
Only with this latest version of pyside are many ETS QT failures fixed.
Did not test this with pyqt.

(For the record, Tasks is currently QT-only.)

I just updated to the latest PySide (1.1.0-2) and am running OS 10.7. My repo is up to date on the master branch as of a few minutes ago.

However, pulling the latest changes on Chaco master branch has fixed the problem. I guess that if someone is running the examples, then they have ETS cloned, and we can assume that if they get the same error, the traceback will lead them to a Chaco update, as it did me.
