Bug#1120636: iagno FTBFS with the nocheck build profile: ../meson.build:51:6: ERROR: Program 'update-desktop-database' not found or not executable

[Helmut Grohne]

Source: iagno
Version: 1:50~alpha-1
Severity: serious
Tags: ftbfs
Justification: fails to build from source (but built successfully in the past)

Attempting to build iagno with the nocheck build profile fails. A build 
fails as follows:

| Got pkg-config variable glib_compile_schemas : /usr/lib/x86_64-linux-gnu/glib-2.0/glib-compile-schemas
| Program /usr/lib/x86_64-linux-gnu/glib-2.0/glib-compile-schemas found: YES (/usr/lib/x86_64-linux-gnu/glib-2.0/glib-compile-schemas)
| Program gtk4-update-icon-cache found: YES (/usr/bin/gtk4-update-icon-cache)
| Program update-desktop-database found: NO

| make: *** [debian/rules:7: binary] Error 2
| dpkg-buildpackage: error: debian/rules binary subprocess returned exit status 2

I suspect that desktop-file-utils is not as optional as debian/control 
claims.
