I still get that at update #3910, too.
so, here's the fix, packaged as a cs this time.
from the preamble:
"Change Set: BrowserSystemCategoryList Date: 30 April 2001 Author: Joern Eyrich
fixes a problem reported by Scott A Crosby when adding a Category in the Package Browser without having a Category selected. changes hardcoded access to category list to use subclass-overridable access method"

Which version of Squeak are you using and what is your latest update?
3.0 VM UNIX. Most recent 3.1 beta image... (all updates).. Not sure how to get the most recent update number out of squeak.
Open up a 'package browser', pick any package group: ('System')
Then for the pane listing individual packages within that group, middle-click to get a menu, select 'add item'. It will ask if you want to add a package called 'Catagory-Name'. Type anything or just click 'OK'...
CRASH into debugger.
