[Bug 1751252] Re: ubiquity crashed in debconf.py:104 with ValueError: invalid literal for int() with base 10: ''

Tue May 1 08:00:30 UTC 2018

Here's the crash with GDK_SYNCHRONIZE=1. It appears to be graphical. And
I have a theory this maybe only happens on machines that default to hi-
DPI (scale 200%) in the live session...
