Package: python2.7 Version: 2.7.3-2 Severity: serious The following change in 2.7.3-2 break python2.7-dbg 2.7.3-1 and earlier versions:
python2.7 (2.7.3-2) unstable; urgency=low
...
* Backport issue #13150: sysconfig no longer parses the Makefile and config.h
files when imported, instead doing it at build time. This makes importing
sysconfig faster and reduces Python startup time by 20%.
...
python2.7-dbg doesn't have _sysconfigdata_d so running
python2.7-dbg fails with:
Traceback (most recent call last):

Since python2.7-dbg 2.7.3-1 depends on python2.7 (>= 2.7.3-1), python2.7
should have a Breaks on python2.7-dbg (<< 2.7.3-2) so that python2.7-dbg
isn't rendered unusable by upgrading python2.7 without upgrading
python2.7-dbg to a version >= 2.7.3-2.
It might be also a good idea to change python2.7-dbg's dependency on
python2.7 to (= ${binary:Version}) as it's already done in experimental.
(I've observed this issue because of the build failure of python-crypto
2.6-4 on the ia64 buildd which has python2.7 2.7.3-5 and python2.7-dbg
2.7.3-1 installed [1])
