Rosviz dies with an assertion failure (ros-pkg ticket #1049)

[hershwg]

I just saw rviz die with the following assertion failure:

{{{
[ERROR] 1236727864.988674000: Received error message in header for connection to [TCPROS connection to [10.0.8.233:58372]]: [Client [/rviz_1236727652780907000] wants topic /mechanism_state to have md5sum 2fc442e85b325b48a5c28bfff1aec3e8, but it has 585c3fbea1beaaf24f6019967910d0c5.

I also managed to get a backtrace from the core file:
