Steps to reproduce:
I was able to reproduce this several times, so it doesn't seem to be a fluke.
What platform? Do you have a crash report?
I'm unable to reproduce anything similar.
Mac OS x 10.6.8Tell me how to generate/find a crash report and I will attach it.
There's a button to show one when an application crashes, or alternatively, you can access past ones via the Console app, under the User Diagnostic Reports section
