[reportlab-users] RE: "Bad file descriptor" after py2exe or Installer

[Michael Porter]

I had a similar problem to this when using cx_Freeze to freeze one of my
apps. This only occurred if I created a Windows GUI app (rather than a
console version) and seemed to be due to the lack of a proper stdout in this
situation. Not sure if this is related but in this case the error happened
when sys.stdout.flush() was being called.
