fix

code from HEAD

if we get a URL like about:blank, or about:home, we fail miserably to lookup the remote source (throw an NPE)

Steps:

1. connect the crossfire client to Firebug
2. open the Ubuntu home page for Firefox (about:home) OR open a new tab and do not navigate to a page (about:blank)
3. select the script in the debug view of the Eclipse client
4. invoke the Open Source... command on it

Happens:

the following NPE

Expected, the source does not open - without an NPE
