This bug is fixed in the development branch. I hope to release in two days.

@Evgeny, sorry for my importunity, but is this bug fixed by recent commits? I still receive these messages.

Did you try yesterday's release? If so, I would need more details about that Activity record - activity_type and other values. Perhaps you could identify the id of that record and then type in the database console: SELECT * FROM activity WHERE id=[record_id] (without the brackets) and post the output here.

Yes, I already use most recent build. How can I find broken record? I tried to check every activity record for few users (both from mysql console and from livesettings) and all records seems readable. Edit: I've added grouped listing of activity_type to question

Problem related to incorrect activity records - some object_id in column 'activity' was filled with nonexistent objects. Probably this happened when I restored site from backup after crush. I was need to execute next query to find broken ids:

SELECT activity.id as aid FROM activity LEFT JOIN askbot_post ON activity.object_id=askbot_post.id WHERE askbot_post.id IS NULL;

Right, this has to do with objects with id == activity.object_id do not exist when they are deleted, but activity records stay. It is not because your database was restored, it is a bug in the code.

It looks like the issue is due to deleted comments. In the past comments did not have revisions in the database, now they do, but still - we delete them the "hard" way - just delete the objects. Questions and answers are deleted the "soft" way - by setting post.deleted = True.
