Launchpad does not generate any .pot templates, it just gets fed the
templates the debian package generates as a result of the build. This is
the only requirement for Ubuntu packages in main which need to have
their translations imported into Launchpad: they must produce a .pot
template during build.

The way this is generally achieved with CDBS-based packages is through
the langpack.mk rule in debian/rules, which takes care of all of this
for you (that's why I included it in the patch). 

You'll find more detailed info at:

By looking at setup.py, I saw that you are using DistUtilsExtra.auto.
IIRC, the auto module takes care of inferring from which files to
extract strings from, without the explicit need of a POTFILES.in file.

For the Ubuntu package you should probably be using the langpack.mk
rule. If I understand it correctly, the problem is when building the
package for Debian, where the langpack.mk rule is not needed and thus
not used?

Could it be that in the Debian version of python-distutils-extra the bug
where .ui files where ignored for extraction has not yet been fixed?

In any case, the DistUtilsExtra version in which bug 451170 is fixed
should recognize the .ui files and extract the translations without the
need of the POTFILES.in file. When I created the patch I tested this was
so. Is that not happening?

Don't worry about this, I'm also learning as I go along :)

I hope this helps.
