rqt_bag occurs a error when I open some bags, but it can work well in other bags. here is the error info:

Traceback (most recent call last): File "/opt/ros/kinetic/lib/python2.7/dist-packages/rqt_bag/bag_timeline.py", line 491, in on_mouse_down TimelinePopupMenu(self, event, topic) File "/opt/ros/kinetic/lib/python2.7/dist-packages/rqt_bag/timeline_menu.py", line 213, in init self.process(action) File "/opt/ros/kinetic/lib/python2.7/dist-packages/rqt_bag/timeline_menu.py", line 262, in process frame.show(self.timeline.get_context()) File "/opt/ros/kinetic/lib/python2.7/dist-packages/rqt_bag/timeline_menu.py", line 85, in show self._viewer = self._viewer_type(self._timeline, self, self._topic) File "/opt/ros/kinetic/lib/python2.7/dist-packages/rqt_bag_plugins/plot_view.py", line 91, in init self.plot_widget = PlotWidget(timeline, parent, topic) File "/opt/ros/kinetic/lib/python2.7/dist-packages/rqt_bag_plugins/plot_view.py", line 176, in init msg = bag._read_message(entry.position) File "/opt/ros/kinetic/lib/python2.7/dist-packages/rosbag/bag.py", line 986, in _read_message return self._reader.seek_and_read_message_data_record(position, raw) File "/opt/ros/kinetic/lib/python2.7/dist-packages/rosbag/bag.py", line 2475, in seek_and_read_message_data_record msg_type = _get_message_type(connection_info) File "/opt/ros/kinetic/lib/python2.7/dist-packages/rosbag/bag.py", line 1571, in _get_message_type message_type = genpy.dynamic.generate_dynamic(info.datatype, info.msg_def)[info.datatype] File "/opt/ros/kinetic/lib/python2.7/dist-packages/genpy/dynamic.py", line 168, in generate_dynamic tmp_file.file.write(full_text.encode()) UnicodeDecodeError: 'ascii' codec can't decode byte 0xe8 in position 574: ordinal not in range(128)

Any suggestion?
