# traceback bugs 1726, 1629,
# and the traceback part of bug 1677, and some related
#(perhaps unreported) bugs.
# The problem was that this is called during pasteBond's addmol
#(due to its addchild), before it's finished,
# at a time when the .part structure is invalid (since the added
# mol's .part has not yet been set).
# To fix bugs 1726, 1629 and mitigate bug 1677, I revised the
# interface to MMKit.update_clipboard_items
# (in the manner which was originally recommented in
#call_after_next_changed_members's docstring)
# so that it only sets a flag and updates (triggering an MMKit
# repaint event), deferring all UI effects to
# the next MMKit event.
