Bugzilla Automation <bugzilla@FreeBSD.org> has asked freebsd-desktop (Team)

Bug 262842: misc/shared-mime-info depends on py-libxml2 but no listed
dependency is given to python
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=262842



--- Description ---
if py-libxml2 is installed shared-mime-info uses it, but since it has no
dependency to python or more importantly py38-libxml2 so it breaks during
upgrade with rest of libxml2 bumps.

shared-mime-info-2.0_3
Depends on     :
	libxml2-2.9.13
	glib-2.70.4_2,2
	gettext-runtime-0.21


errors out with cython version error failing to load libxml2mod
