Debugging of multitaprocessing app on Fedora 25

Hi,

I'am trying to debug the b/m piece of code, however each time after 2 oraz 3 second I receive the error: KeyboardInterrupt

Full exception is at the bottom of this post.

The problem did not ocured on Fedora 21. I am using the follwoing Pycharm version: 2017.14, build PC-171.4694.25, JRE 1.8. 

<code>

import time, multiprocessing

def the1():
while 1:

# here is the breakpoint
print("I am working in the background {:s}" . format(multiprocessing.current_process().name))
time.sleep(1)

def main():
t1 = multiprocessing.Process(target=the1, name='ARCHITECT')
t1.start()

if __name__ == "__main__":
main()

</code>

Full error:
