0002500: In6713 Sometimes a Legitimate request generates DNU PseudoClass>>isTraits .
This is a late night bug and I do not remember specifially what I did to get to the DNU.

However:
In a workspace.

PseudoClass isTraits answers false
but
PseudoClass new isTraits will give the DNU message.

Something is SystemNavigation had an instance of PseudoClass in an variable called "aClass"

Again this is a early heads up.

In the light of day...

To encounter this bug

From file list
find a change set.
request a code browser on it.
select a method
from the custom menu ask for implementors.

This got the DNU to come up.

Frustratingly the next time I did the very same thing I did not run into DNU but got the implementors list I expected.

I've uploaded the debug log.
