Bug#940087: FTBFS: test-prompt: Method "Prompt" with signature "s" on interface "org.freedesktop.Secret.Prompt" doesn't exist

[Simon McVittie]

Source: libsecret
Version: 0.18.7-1
Severity: serious
Tags: ftbfs
Justification: fails to build from source (but built successfully in the past)

During build-time tests, for example in
<https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/libsecret.html>
and
<https://tests.reproducible-builds.org/debian/rb-pkg/experimental/amd64/libsecret.html>:

> **
> ERROR:libsecret/test-prompt.c:239:test_perform_vanish: assertion failed (error == NULL): Method "Prompt" with signature "s" on interface "org.freedesktop.Secret.Prompt" doesn't exist
>  (g-dbus-error-quark, 19)

I can reproduce this locally and am looking into it. I think it's just
a race condition in the tests.
