Dear maintainer(s),

With a recent upload of rust-webbrowser the autopkgtest of
rust-webbrowser fails in testing on i386 when that autopkgtest is run
with the binary packages of rust-webbrowser from unstable. It passes
when run with only packages from testing. In tabular form:

                        pass            fail
rust-webbrowser        from testing    1.2.4-1
all others             from testing    from testing

I copied some of the output at the bottom of this report.

Currently this regression is blocking the migration to testing [1]. Can
you please investigate the situation and fix it?
