0003150: In 7002 Asking for priorVersions causes browsing some primitive methods to get a DNU
For this one:

in a fresh 7002

from preferences request preference panes in browsers

from the annotation morph request priorVersions (and nothing else) as the annotations and apply.

call up a browser on the implementors of
primMouseButtons

there are two and the one for EventSensor comes up selected first
Switch to the one for InputSensor.

The DNU comes up.

The DNU is quite insistant.
The culprit is in:

VersionsBrowser>>scanVersionsOf: method class: class meta: meta category: category selector: selector

 'bf 2/13/2006 00:14
VersionsBrowser>> scanVersionsOf:class:meta:category:selector:
{init & update}'

The added temp var cat is nil when its size is asked for.

I haven't attempted further study. Bert will be able to find the problem faster.

A debug log is uploaded. Though I suggest just recreating the sucker and tracking stuff down in the debugger.
