60 I've seen some segmentation faults lately again and rechecked the
\r
61 python bindings and while I actually found and fixed some error
\r
62 handling issues I overlooked last time, I think I also found a bug in
\r
63 notmuch_database_close.
\r
65 The problem can easily be reproduced with the following program:
\r
72 db_path = os.path.expanduser('~/Maildir')
\r
75 with notmuch.Database(db_path, mode=notmuch.Database.MODE.READ_WRITE) as db:
\r
79 The top of the resulting stack trace is
\r
82 #0 0x00007fa2b6ac8104 in Xapian::WritableDatabase::commit() ()
\r
83 from /usr/lib/libxapian.so.22
