** Description changed:
[Impact] importing pytables fails due to a missing dependency. The error
message is gives no indication of what is missing
[Development Fix] in precise the dependencies of pytables are correctly
specified
[Stable Fix] the cause of the error in natty and oneiric is an error in the
dh_shlibdeps call which causes shlib:Depends and shlib:Recommends to be not be
filled correctly
While the fix is not really necessary for oneiric due to hdf-5 having changed
so that the Dependency is really optional, it still missing Recommends and we
need to update it to ensure a proper upgrade path.
[Test Case]
have liblzo2-2 *not* installed
apt-get install python-tables
python
import tables
expected result: successful import
result on natty:
ImportError: /usr/lib/python2.7/dist-packages/tables/hdf5Extension.so:
undefined symbol: H5T_STD_U8BE_g
[Regression Potential] only dependencies are changed so no regressions are
likely
+ also pytables contains an extensive testsuite, while it is not run during
build, it can be executed with:
+ python /usr/share/pyshared/tables/tests/test_all.py
+ it passed with the updated packages
original report
When I import tables without liblzo2-2 I get a Traceback:
jvb@weasel:~$ python -c "import tables"
Traceback (most recent call last):

After installing liblzo2-2 - no traceback:
