You may notice an error which does appear erratically but most of the time, same on trunk demo and locally. This happens because sometimes the BREAD_CRUMB_TRAIL session attribute is empty or null. "Why not alway?" you might ask. I had no time to investigate but I guess because there is no bread crum trail when coming from catalog, and for some weird reasons, it's sometimes there.
Anyway my fix is simple, if there is no BREAD_CRUMB_TRAIL in session I bypass the bread crum block in BreadCrumbs.ftl. It's not perfect but look far better
