libpath-tiny-perl's 0.148-1 upload breaks 
libconfig-model-itself-perl's test suite in autopkgtests.
(Or maybe libpath-tiny-perl's involvement is just a coincidence?)

Interestingly this does not happen when I _build_ the package locally 
but it also happens during a local autopkgtest run.

Note 1: wr_root/ is missing during autopkgtests. But adding it to 
        debian/tests/pkg-perl/smoke-files is not enough.
Note 2: The failing tests use Config::Model::Tester::Setup (from 
        libconfig-model-tester-perl) with
#v+
    71	    my $wr_root = path('wr_root')->child($name);
#v-

which looks a bit like https://github.com/dagolden/Path-Tiny/commit/07dc0eef61ecd748821c3fdd135f72419b257fa3

Or maybe Path::Tiny's mkdir/mkpath/remove_tree are used somewhere 
else in the Config::Model universe with a string instead of a hashref 
:)


Cheers,
