Hi,
I can confirm this, been having the same issue. I worked around it 
temporarily by changing some python-packages and adding some to a 
temporary channel and guix pulling to the commit just prior to the 
32ba87c14 that you mention. In case anyone is helped by it; the channel 
is here: https://github.com/methuselah-0/my-guix-packages

Best regards,
David
