[squeak-dev] Problem with OBPackageBrowser

Hi,
I don't know if this belongs to this list, but I don't know of any
other where I can get help on this.
I'm having different behaivor between OBSystemBrowser and
OBPackageBrowser, in this case:

OBSystemBrowser new
        open;
        jumpTo: (OBClassCategoryNode on: 'Sushimoto')

This works fine, but:

OBPackageBrowser new
        open;
        jumpTo: (OBClassCategoryNode on: 'Sushimoto')

Throws a DNU #isDescendantOfClass: in #isAncestorOf:using:

I'm using lates OmniBrowser-Full (0.25) from Universes in a 3.10 image.

Thanks for any help,
Esteban
