This is a bug in the woody libmysqlclient10 package, which should not have
been using errno in this way.
It also only occurs when the TLS-enabled glibc is used, which is only the
case if you are running a glibc kernel.
So, partial upgrades are supported if you don't reboot to a 2.6 kernel prior
to also upgrading libmysqlclient10 (or mysql-server). Cc:ed to the glibc
folks, so they can consider how this should be handled.
