I can reproduce it on my Mac. The croak happens while it is attempting to raise the exception about a bad file descriptor. Unfortunately, in PyErr_Restore the call to PyThreadState_GET() returns NULL which means that _PyThreadState_Current is NULL. I see no differences between pystate.[ch] in the 2.5 and 2.6 branches. There must be something different about the way PyThreadState_Swap or PyThreadState_DeleteCurrent are used. Those are the only two routines which appear to set it.
Did this not happen with 2.5.2?
Wild guess: the bug might be related to http://bugs.python.org/issue1683. From the top of my head it's the only major change in the thread state code that I can recall. Christian
