[Pythonmac-SIG] Problems with py2app and qt

[aditya bhargava]

Brilliant...it turned out that the Qt libraries were being loaded *twice* –
once from inside the bundle and once from the libraries on my computer.

The hack fix was to create a qt.conf file inside Contents/Resources and give
it a bad path...this way only the libraries inside the bundle are being
loaded. Putting this inside qt.conf:

[Paths]
Plugins = bollocks

Did the trick :)

Thanks Emanuele!
