Sure.

The change done in libconfig-model-tkui-perl 1.370 did break libconfig-model-
itself-perl 2.016 (the API change are backward compatible, the class 
inheritance, less so :-( )

I've released libconfig-model-itself-perl 2.018 with a change that fixes the 
tests with libconfig-model-tkui-perl 1.370 (but probably break with 1.369).

The log from auotpkgtest [1] in  the setup that should work shows this error:

ok 3 - Read all models from wr_root/load_write_itself/lib/Config/Model/models
Configuration item 'application:fstab model' has a wrong value:
	reference type does not know 'Fstab'. Expected 'Itself::Application' or 
'Itself::CargoElement' or 'Itself::Class' or 'Itself::CommonElement' or 
'Itself::CommonElement::Assert' or 'Itself::CommonElement::WarnIfMatch' or 
'Itself::ComputedValue' or 'Itself::ConfigAccept' or 'Itself::ConfigReadWrite' 
or 'Itself::ConfigReadWrite::DefaultLayer' or 'Itself::Element' or 
'Itself::MigratedValue' or 'Itself::Model' or 'Itself::NonWarpableElement' or 
'Itself::WarpOnlyElement' or 'Itself::WarpValue' or 
'Itself::WarpableCargoElement' or 'Itself::WarpableElement'
# Tests were run but no plan was declared and done_testing() was not seen.
# Looks like your test exited with 2 just after 3.
Dubious, test returned 2 (wstat 512, 0x200)

This looks like cme is able to find the file /usr/share/perl5/Config/Model/
system.d/fstab , but is not able to load /usr/share/perl5/Config/Model/models/
Fstab.pl. Even though both files are provided by libconfig-model-perl. 

Given that I cannot reproduce this issue on my system, I guess that the setup 
of perl library in autopkgtest is different than the default setup.  I need to 
check how these files are found.

In any case the root cause for the failure of libconfig-model-itself-perl 2.018 
with libconfig-model-tkui-perl 1.370  is not the regression brought by 
libconfig-model-tkui-perl 1.370


All the best
