test failure with MU_DEFAULT_SCHEME=maildir

Hi,

I am getting test failures when configuring mailutils with
MU_DEFAULT_SCHEME=maildir [1]. The test log makes the reason obvious:

[...]
spawn /bin/cat /var/tmp/portage/net-mail/mailutils-3.18/work/mailutils-3.18/mail/testsuite/data/spool/folder/alice
/bin/cat: /var/tmp/portage/net-mail/mailutils-3.18/work/mailutils-3.18/mail/testsuite/data/spool/folder/alice: Is a directory
FAIL: Contents of /var/tmp/portage/net-mail/mailutils-3.18/work/mailutils-3.18/mail/testsuite/data/spool/folder/alice
[...]

Any suggestions?

Thank you
