Could you mail the offending file to me off list along with an indication of 
roughly which line(s) appear to trigger the problem please.

The BDI-4.38 uses a 2.6.12.6-rtai kernel and there has been a couple of 
updates uploaded to the repository at http://bdi4emc.ourproject.org/debian/ 
which might cure the problem.. By the sounds of it, it is an intermittant bug 
which are often a pain to track down. The most likely area is the trajectory 
planner getting tripped up - Matt has been busy rewriting this section 
(thanks Matt) and may have fixed the problem in the process.
