[Pythonmac-SIG] "Fatal Python error: PyThreadState_Get: no current thread"

[Richard Jones]

I've just switched from running py2app with -A to not using it. After 
fleshing out the "includes" option so that my required modules were 
included, I finallly got the app to start up. It promptly quits, with 
the following message:

Fatal Python error: PyThreadState_Get: no current thread
Abort trap

My app is a simple GUI thing which controls Zope through the 
zdaemon.zdctl module. It's attached. The Zope libs (and some supporting 
libs) are installed in the app's Resources folder in a "runtime" 
subdirectory (historical name, will eventually change to Zope ;)

As I mentioned, this works OK when I invoke py2app with -A but it 
breaks when I run it for real.

I'm not using threads in my app, but Zope does use threads when it's 
running. The invocation of the zdaemon.zdctl code should not create any 
threads that I'm aware of. I'm currently working through a process of 
elimination to see whether I can narrow down to a particular suspect.

Does anyone have any ideas what might cause this?
