Bug#1035983: libsoap3 (and libsoap2) autopkgtests are flaky: Address already in use: AH00072: make_sock: could not bind to address 127.0.0.1:47524

Severity: normal

Libsoap2 & libsoap3 triggers autopkgtest run when updating other packages,
such as samba. And on almost every samba upload, for quite some time, I
have to reschedule one or another libsoap autopkgtest run due to the same
failure, like in current version:

FAIL: libsoup-3.0/auth-test.test (Child process exited with code 1)

And subsequent tests in the category fail too, due to the same issue.

Right now we can't migrate samba to testing due to this test failure.
Usually it is sufficient to reschedule the test once, sometimes it
goes on after second attempt.

Can you please take a look?
