Habmin item list empty


after moving to 1.8.1, habmin does no longer display my persistence-stored items, the list remains empty (using latest habmin sourcefiles and the 1.8.1 zwave binding).
FWIW, I moved to the 1.8.1 raspian package and was on a manual install before, so some stuff like file access rights have changed. But as it’s a standard 1.8.1 now (and working), the OH setup should be right, I guess.
I’ve re-installed habmin and experimented a lot (package and manual install, old and new jars, …), but I can’t get it to work.
Sitemaps and bindings are still accessible through habmin, but the items are not (neither config nor persistence tab).

I get many null pointer exception errors in the openhab log when accessing the habmin URL, beginning with the one below.
@chris: any idea ?

Although it doesn’t help you a lot: habmin is working fine after upgrading to 1.8.1 (apt-get install).
Persistence is showing up correctly (rrd4j and mapdb), items are showing up fine …

RPi2, Raspbian Jessie, all bindings 1.8.1, habmin 1.7.0

Good luck.
