[PyQt] Debugging PyQt access violations in Windows??

Can anyone give me advice on PyQt debugging techniques?
I am using Eclipse 3.3 with PyDev extensions for development.
I specifically have problems with access violations.
Something goes wrong (normally when I exit my PyQt app by closing it)
and I get a
Visual Studio Just-in-time debugger window saying "An unhandled
exception occured in python.exe"
If I open Visual Studio and look at the output, it typically looks
something like this:
"Unhandled exception at 0x00b604df in python.exe: 0xC0000005: Access
violation reading location 0x28c02e5c."
Obviously this does not help me much.
My PyQt app has a Main Window and a bunch of child dialogs. I suspect
there is some garbage collection
issue when I close the Main Window. How do I debug this??
Please help me... this year is getting too long.... :(
