Next/prev buttons in raw view don't work in Noetic #95

Closed JStech closed 3 years ago

JStech commented 3 years ago

In Noetic, after loading a bag and showing the raw display of a message, clicking the arrow buttons for next or previous message at the top of the message pane causes this error:

Traceback (most recent call last):
  File "/opt/ros/noetic/lib/python3/dist-packages/rqt_bag/plugins/topic_message_view.py", line 87, in navigate_previous

AttributeError: module 'rosbag.bag' has no attribute '_mergesort'

Got a similar error again, this time I think it was while the bag was being opened--no messages ever showed up, and then I saw this when I closed the window.

Exception in thread Thread-8:

Sorry, I realized this is probably a duplicate of #90.
