[Pythonmac-SIG] Sqlite database drivers with py2app?

[Michael McCracken]

Hey, I'm glad that was useful!

Another thing that probably won't affect you, but in case it does -
make sure you keep a reference in your python script to the
QtApplication that you create.
ie, do 'app = QApplication(sys.argv)' instead of just 'QApplication(sys.argv)'.

Otherwise the QApplication will get garbage collected and weird things
happen, including forgetting where to look for plugins!

Feel free to ask about PyQt4 here, as I'm working on porting a PyQt
application to OS X now, and may have run into other problems already.

Cheers,
-mike
