Description Greg Watson

In some cases, when I start a resource manager, the columns displayed in the jobs view are all set to some minimum size. This seems to occur on the jobs view that is not currently visible when the RM is started. 

If the RM is then stopped, I get the following NPE:

I have this issue with squished columns as well on Ubuntu Linux.  In some cases after adjusting a column all of the columns gradually re-size themselves so all but the rightmost are as small as possible.
