Hi, I am running into an error that I bet has a simple solution. I would appreciate any help.  Thanks.

I am running Brad Chapman's LIMS extension locally on Ubuntu 12.  I also installed it as a service under /etc/init.d/chapman-galaxy using contrib/galaxy.debian-init .  It works when I run it directly (./run.sh --reload)

When I run a version of Galaxy without nglims as a service, there is no error.
When I run a version of Galaxy with nglims, not as a service (run.sh), there is no error.
However, when I run the same version of Galaxy with nglims as a service, there is an error.  I don't understand well enough what the difference is when I run it as a service to diagnose this problem.  The lines leading to the error from the log file is below.  Something to do with yaml not being loaded, but I know I installed python-yaml through aptitude.
