The following example illustrates the problem:

bagira:~/python/dist/src/Lib> cat tt/xx
hello=None
import yy
print "in xx:yy imported"

bagira:~/python/dist/src/Lib> cat tt/yy.py
from __main__ import hello
print "in yy: yy imported "

this works by itself:

bagira:~/python/dist/src/Lib> ../python tt/xx
in yy: yy imported
in xx:yy imported

But breaks under pdb

 bagira:~/python/dist/src/Lib> ../python -m pdb tt/xx 
 > /home/ilya/python/dist/src/Lib/tt/xx(1)?()
 -> hello=None
