I went a bit further: The issue is not specifically glib-related, but can be reproduced with any package using the following:
(search-path-specification
(variable "XDG_DATA_DIRS")
...)
Hence, the following manifest can reproduce the problem:
(specifications->manifest '("fontconfig"))
even though fontconfig does not depend on glib (but does search XDG_DATA_DIRS).
