[Pkg-nagios-devel] Bug#1013512: icinga-php-library 0.9.0-1 breaks CSS generation for icingaweb2 2.9.5-1

[llamaonaskateboard]

Package: icinga-php-library
Version: 0.9.0-1
Severity: critical

icingaweb2 2.9.5-1 fails to generate CSS as a result of icinga-php-library 0.9.0-1 being migrated to Debian testing.

Operation on an invalid type
#0 /usr/share/icingaweb2/library/vendor/lessphp/lib/Less/Tree/Expression.php(51): Less_Tree_Operation->compile()
[snip]
.fa-li {
!! left: calc(var(--fa-li-width, 2em) * -1);

Refer to upstream issue at https://github.com/Icinga/icinga-php-library/issues/13
It appears icinga-php-library 0.9.0 may have a dependency on icingaweb2 2.10.2 which is currently blocked from Debian testing.
