I have verified that the tests from 0.12.1 pass with either the 0.12.1 or
0.12.2 code, and the tests from 0.12.2 fail with either the 0.12.1 or 0.12.2
code, so there is no regression in functionality here. Nevertheless, there
is a regression in test coverage since the s390x autopkgtest can now no
longer be used to catch bugs in glymur's dependencies.
I have not tracked down whether this is a test bug or a bug in the code, it
could be either.
