Hello,

I updated my Trunk image this morning and just got an emergency
evaluator popping up. I seem to have a bug in a hasContentsInExplorer
method of one of my classes, but I didn't think that would lead to an
emergency...

At least it continues quite normally if I press any key. Got a bunch
of debuggers and could fix the error there.

Attached you find the SqueakDebug.log. Now I will type the stack trace
from the evaluator... Is there a way to copy that except for taking a
screenshot?
