Thanks Nicolas,
I am not able to post the diff due to the personal nature of the data. However, I can say that with the commit, the tags in the #+TAGS line is missing. Also, a link to one of the org files is missing.
Would it be possible to revert this change? This is such a critical bug and it really disrupted many of ours personal workflows. It also embarrassed us towards our colleagues, families, and friends who held the view that proprieatary solutions are better.
In general, it is preferable to have a test suite which should pass before releasing these commits. Yes, there is MELPA stable but not every package is on MELPA.
