Bug#1006658: libobject-pad-perl breaks libtickit-widget-scrollbox-perl autopkgtest: malloc_consolidate(): unaligned fastbin chunk detected

Dear maintainer(s),

With a recent upload of libobject-pad-perl the autopkgtest of 
libtickit-widget-scrollbox-perl fails in testing when that autopkgtest 
is run with the binary packages of libobject-pad-perl from unstable. It 
passes when run with only packages from testing. In tabular form:

                        pass            fail
libobject-pad-perl     from testing    0.61-1
libtickit-widget-scrollbox-perl from testing    0.11-1
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 of 
libobject-pad-perl to testing [1]. Due to the nature of this issue, I 
filed this bug report against both packages. Can you please investigate 
the situation and reassign the bug to the right package?
