[Evolution] How to crash evolution

[Guy Steven <rgs etive southern co nz>]

The mail component of Evolution (anoncvs as of a day ago) will crash if
the mail configuration window is opened and then closed by using the
window manager close window control in the frame. 
A back trace from gdb  reveals:

Gtk-CRITICAL **: file gtkobject.c: line 1172 (gtk_object_unref):
assertion `GTK_IS_OBJECT (object)' failed.

Program received signal SIGSEGV, Segmentation fault.
