Please enhance the error messages when trying to work with a camel context with 0 routes defined

Hi,

When there are 0 routes in a camel context, the fuse ide generates a java exception when clicking on "start tracing" or "edit routes". Could this be changed to display a message such as "No routes are defined"? I noticed there are also errors generated when clicking on the camel context itself, however, one wouldn't know this unless you had the error log open. Otherwise, the messages are rather unhelpful as to what went wrong. See attached samples and test case.
