Hiya,
I noticed that commit 687366b920caa5de6ea0b66b70cf2a11e5399f7b
breaks things with Database.get_all_tags:
-------------------------------------->%-------------------------------------
AttributeError Traceback (most recent call last)
/home/pazz/projects/alot/<ipython console> in <module>()
/usr/local/lib/python2.7/dist-packages/notmuch/tag.pyc in next(self)
86 # No need to call nmlib.notmuch_tags_valid(self._tags);
87 # Tags._get safely returns None, if there is no more valid tag.
---> 88 tag = Tags._get(self._tags).decode('utf-8')
89 if tag is None:
90 self._tags = None
AttributeError: 'NoneType' object has no attribute 'decode'
------------------------------------%<---------------------------------------
The reason is that the Tags.next() tries to decode before it tests if tag is None.
Now, we _could_ apply a patch like this one here:
---------------------------------->%-----------------------------------------
diff --git a/bindings/python/notmuch/tag.py b/bindings/python/notmuch/tag.py

But as Carl sais, we cannot guarantee that a tag is utf8 encoded anyway.
So i'd suggest we just revore the commit in question.
best,
/p
