Calling Message.tags_to_maildir_flags() when the database has been opened with a relative path results in a corrupted filename entry in the database. The actual filename is changed properly but the filename in the database gets the relative path prepended.
As I understand it's expected that the database path should be absolute but corrupting the database when the path is relative sounds dangerous. Attached is a python script showing the problem. Run it as follows: python ./retag_bug.py db_path +tag,-tag search_query Also attached is the output showing the problem. -------------- next part -------------- An HTML attachment was scrubbed...
