what do you mean by crash? do you have any console output?

goats works with libgnomeprintui-2.4, so i've fixed the dep in the ebuild.
it should not need to downgrade libgnomeprintui anymore.

The goats ebuild downgrades libgnomeprintui as a dependency, but not
libgnomeprint.
 Consequently, the libgnomeprintui ebuild crashes because it's dependency
(a downgraded libgnomeprint) isn't met.

Perhaps the pre-2.4 libgnomeprintui ebuild needs a check for the correct
version of libgnomeprint?

Sorry for the confusion.  I should have been more specific regarding the
crash.

how do you mean crash ?

maybe we should make the dep in libgnomeprint ui stricter to =<pack>* instead
of >=

Crash as in, "the compile fails because a library dependency isn't met".
Pre-2.4 libgnomeprintui will not compile if libgnomeprint-2.4 is installed.
 I believe your suggested fix is correct.

Sorry about not providing console output of the crash.  I assumed the bug
was an obvious one.  Probably the libgnomeprintui ebuild should contain:

RDEPEND="=gnome-base/libgnomeprint-${PV}*"

Instead of:

RDEPEND=">=gnome-base/libgnomeprint-${PV}*"

crash i think of segfaults etc. Ebuilds can fail, i don't consider it
'crashing'

anyway, i fixed the deps as proposed to be on the safe side.

Thanks for your report.
