[Pythonmac-SIG] AEDesc error: Unsupported Type

[Ben Pedersen]

Hello all,
Working with py-appscript to automate testing and I'm getting an error
deep in aemreference/aemcodecs.  Following are the trace and some code
to reproduce.  The error seems to be caused by calling a separate
function in a parent class that returns a reference to an appscript
object -  commenting the last line of setUp and uncommenting the 2
lines above it lead to working code.  That's an acceptable workaround,
but I'm very curious what is causing the issue ... does application
object get cleaned up prematurely?

Traceback (most recent call last):
