[R-pkg-team] Bug#1008949: r-cran-bbmle: autopkgtest needs update for new version of rmatrix: warning shows up in compared data

Source: r-cran-bbmle
Version: 1.0.24-3
Severity: serious

Dear maintainer(s),

With a recent upload of rmatrix the autopkgtest of r-cran-bbmle fails in 
testing when that autopkgtest is run with the binary packages of rmatrix 
from unstable. It passes when run with only packages from testing. In 
tabular form:

                        pass            fail
rmatrix                from testing    1.4-1-1
r-cran-bbmle           from testing    1.0.24-3
versioned deps [0]     from testing    from unstable
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 rmatrix to 
testing [1]. Of course, rmatrix shouldn't just break your autopkgtest 
(or even worse, your package), but it seems to me that the change in 
rmatrix was intended and your package needs to update to the new situation.

If this is a real problem in your package (and not only in your 
autopkgtest), the right binary package(s) from rmatrix should really add 
a versioned Breaks on the unfixed version of (one of your) package(s). 
Note: the Breaks is nice even if the issue is only in the autopkgtest as 
it helps the migration software to figure out the right versions to 
combine in the tests.

[0] You can see what packages were added from the second line of the log 
file quoted below. The migration software adds source package from 
unstable to the list if they are needed to install packages from 
rmatrix/1.4-1-1. I.e. due to versioned dependencies or breaks/conflicts.
