I can confirm that the package version from bionic-proposed solves the
problem.
During an installation I used Dell 2715Q with settings as in the
screenshot attached (single monitor mode, 200% scaling).
# the updated package
apt policy ubiquity

Before adding "deb http://archive.ubuntu.com/ubuntu/ bionic-proposed
main restricted" to sources.list and doing `apt install ubiquity` I had
this in syslog:

Title:
[regression] ubiquity crashed in debconf.py:104 with ValueError:
invalid literal for int() with base 10: ''
Status in cairo:
Confirmed
Status in OEM Priority Project:
Triaged
Status in cairo package in Ubuntu:
In Progress
Status in ubiquity package in Ubuntu:
Fix Released
Status in cairo source package in Bionic:
In Progress
Status in ubiquity source package in Bionic:
Fix Committed
Bug description:
* Impact
The Ubuntu installer crashes on some machines (seems more often on hiDPI
machines (QHD/UHD etc)).
* Test case
Try installing Ubuntu on an hidpi machine, it should complete installation
instead of crashing.
* Regression potential
The fix in ubiquity touches the code handle uid drop/privilege, that can have
unexpected side effects so we need proper/complete testing of the installer
----------
Update: Actually the crash occurs on slow-ish systems due to a race
condition. It's not strictly only hi-DPI machines - that's just the
most common place it is experienced.
