[Sugar-devel] Bug 1752550

[James Cameron]

Thanks to Alex Perez, this was an ImportError in gwebsockets 0.5 when
used with Python 2.  gwebsockets had been ported to Python 3 without
support for Python 2.

Always.  Reproducible in the default Fedora image too, not only SoaS.

Boot the image.

File ~/.sugar/default/log/shell.log contained the traceback.

I was right.  I urge "install and use" testing before package release.

Packages of Sugar 0.114 were the trigger, but the problem was in
gwebsockets.  It is a sign of our lack of effort that the problem was
not detected earlier.
