[tycho-user] NPE in building p2 update site with 0.16.0.SNAPSHOT

Hi,

I'm trying to setup a tycho build for the e4 tools project. During the
build of the p2 update site  with 0.16.0.SNAPSHOT I receive an error
similar to https://bugs.eclipse.org/bugs/show_bug.cgi?id=386133.
Details below.

The bug is marked as fixed. Is this something else?

Best regards, Lars
