Bug#1023122: gnucash: FTBFS with ICU 72.1

[László Böszörményi]

Source: gnucash
Version: 1:4.12-1
Severity: important
Usertags: icu72_1
Tags: ftbfs upstream bookworm sid

Hi,

ICU 72.1 is in experimental and I would like to start its transition
in Sid. Your package fails to build with it, actually one of its
self-tests doesn't pass anymore. Relevant lines:
