Thanks a lot for this @claudep. I haven't forgotten. I am trying to fix the test problem in Python 3.

Yes, would be great if you could sort the xapian 4/python 3 install issue!

This has been merged to master as I was able to fix the Python 3 install issue. Essentially, during installation, we were running Python while we were in a removed directory. This was an issue in Python 3 (Python issue 22834). The fix was to cd to another directory before running Python.

This fixed all issues for upgrading for Xapian 1.4.1 and therefore Xapian-Haystack now supports Xapian 1.4.1. Thanks again for the help @claudep.
