The bug in python-netcdf comes from a change in python-numpy. The last binNMU of python-netcdf having occurred on 2012-03-08, it was built against python-numpy 1:1.5.1-4, whereas sid/wheezy currently have 1:1.6.2-1. This is confirmed by the following tests: - install python-netcdf and python-numpy as currently in sid => the testcase provided by Julian Taylor in #685812 fails (as already noted by Julian) - downgrade to python-numpy 1:1.5.1-4 without recompiling python-netcdf => the testcase succeeds - upgrade back to python-numpy 1:1.6.2-1 then recompile python-netcdf => the testcase succeeds (as already noted by Julian) So my understanding is that the problem comes from some ABI breakage in python-numpy, which was not followed by a recompilation of python-netcdf. What I don't understand however is that the python-numpy maintainers/upstream claim that there was no ABI breakage between 1:1.5.1-4 and 1:1.6.2-1 (see the Provides field of python-numpy). Either I am missing something or that claim is wrong. As a side note, a call to dh_numpy should be added to debian/rules in python-scientific (as noted by lintian); in the present case it would however not have helped, as evidenced by the above paragraph. -- .''`.
