Can you make a small, self-contained test case? The SystemError should be a normal exception and might indicate a deeper problem.

Create a module z.py whose contents are:

#z.py import sys import imp

sys.stdout = None try: y = imp.load_source('x.y', 'x/y.py', open('x/y.py')) except: raise else: print "printing should raise an AttributeError, but doesn't"

#end of listing for z.py

Create a module x/y.py whose contents are: (x/init.py not required)

#x/y.py import sys

#end of listing for x/y.py

Running z.py in Python 2.3 and 2.4 produces: printing should raise an AttributeError, but doesn't

Running z.py in Python 2.5b2 produces: Traceback (most recent call last): File "test.py", line 7, in y = imp.load_source('x.y', 'x/y.py', open('x/y.py')) File "x/y.py", line 1, in import sys SystemError: Parent module 'x' not loaded
