I'm using hudson for some time. Few weeks ago I started using build
descriptions for some purposes. Now I found that when I shutdown hudson
and start it again, all descriptions are away.

Steps to reproduce:
I'm using hudson 1.184 but I found this first in 1.169. I'm using hudson
in Tomcat 5.5.

1) create a job
2) select job - you see status page of job
3) start one build and wait for finish
4) select build in Build history list - you see Status page of build
5) press Add description on right side and add some description
6) return to job Status page and check your description in Build history
list
7) shutdown Hudson with Hudson->Manage Hudson->Prepare for Shutdown
8) restart tomcat
9) check job page and Build history list - on my system there is no
description anymore
