[scribus] Bug in python interpreter on scribus 1.3.3.13 ?

[Stefano Danzi]

I'm writing a BIG python script for my company.

On this script I have a lot of print(...) to display debug messages.
If I use scribus in console mode (command line switch --console) all 
work fine.
If I use scribus in normal mode script die unexpectly.

I placed a # before each print() and now script work fine in normal mode.

It's a known bug???

bye
