Hi,

I'm trying to convert a bagfile into pcd files using bag_to_pcd. But 
everything I get is

[ERROR] [1297703460.328842013]: You requested a transform at time 
1292497206.348,
  but the tf buffer only contains a single transform at time 1292497207.122.
  When trying to transform between /head_tof_link and /base_link.

What's wrong? Replaying the bag file using rosbag play seems to work 
correctly.

Best regards,
Georg
