[Pythonmac-SIG] Problems with py2app and qt

[aditya bhargava]

It's a memory issue with Qt I think. The other interesting thing is, this
problem doesn't occur if I build the app in alias mode with the -A
flag...but of course that's not too useful if I want to distribute
applications.

Here's the issue I get:


Exception:  EXC_BAD_ACCESS (0x0001)
Codes:      KERN_PROTECTION_FAILURE (0x0002) at 0x00000000
