Database logged by mongdb_log_cimg cannot be played.

Logging compressed image as:

$ rosrun mongodb_log mongodb_log.py /left/image_raw/compressed
Adding topic /left/image_raw/compressed
DETECTED compressed image topic /left/image_raw/compressed, using fast C++ logger
^Ctajima@nextage1:~/Codes/ros/hydro/src/mongodb_store/mongodb_log/src$ rrun mongodb_log mongodb_log.py /left/image_raw/compressed
Adding topic /left/image_raw/compressed
WARNING: topic [/left/image_raw/compressed] does not appear to be published yet
DETECTED compressed image topic /left/image_raw/compressed, using fast C++ logger

And playing it back as:

$ rosrun mongodb_store mongodb_play.py /left/image_raw/compressed
Playing back topics set([u'left_image_raw_compressed'])
Exception in thread Thread-4:
Traceback (most recent call last):

    self.publisher = rospy.Publisher(documents[0]["_meta"]["topic"], msg_cls, latch = documents[0]["_meta"]["latch"], queue_size = 10)
KeyError: 'topic'

The database has no _meta: {topic, latch} field, I guess that's why.

Environment: Ubuntu12.04 + Hydro, mongodb_store ver. 0.1.12

Thank you.

I have the exact same error but on Ubuntu 14.04 + Indigo using mongod ver2.4.9. Any updates?
