Indeed. This is fixed or at least improved in commit
babc2c80a7e1f1b5e72fd1685ef6604b93157a8e. Now the message looks like:
--8<---------------cut here---------------start------------->8---
ice-9/psyntax.scm:1422:32: Syntax error:
gnu/packages/idutils.scm:42:4: package: invalid field specifier in form (synopsis "Identifier database utilities" foo)
