[R-SIG-Mac] R.app editor crash

[Peter Dixon]

Hi -
I consistently get a segfault error when I use the built-in editor with a dataframe:

This happens when the editor is invoked from the workspace browser, and then the window is closed.
Editing functions works fine, though.
Is this a known bug or maybe something in my system?
Thanks.
