I got
pyqt 4.10.1-1
ipython 0.13.2-1
Python 3.3.1
python-pyzmq 13.0.2-1
pyqt 4.10.1-1

What do you get from:

import socket
print(socket.gethostname())
try:
    socket.gethostbyname_ex(socket.gethostname())
except Exception as e:
    print(e.__class__.mro())

[ginobvhc]

the truble was in the file local interfaces.py
socket.gethostname() works

the command on line 33

LOCAL_IPS.extend(socket.gethostbyname_ex(socket.gethostname())[2])

give me [Errno 110] conection time out

then i commented the lines 32-35

localinterfaces.py

# <snip>

#try:
    # LOCAL_IPS.extend(socket.gethostbyname_ex(socket.gethostname())[2])
#except socket.gaierror:
#    pass

# </snip>

this solved eventualy for my but i think there is anoter solution for the problem
I hope this information will be usefull for the dev-team
and I REALY SORRY FOR MY ENGLIS OF 4th GRADE

[minrk]

Please reun the command I requested, and post the output

[ginobvhc]

output :
netarch
[ class 'TimeoutError' , class 'OSError' , class 'Exception' , class 'BaseException' , class 'object' ]
< does't allow in this page

[minrk]

Okay, I'll add an extra catch there.

This was fixed by #3354.
