Deleting a desktop icon causes gmc to segfault

[Daniel Burrows <Daniel_Burrows brown edu>]

Package: gmc
Version: CVS 03-31-99

  If I delete an icon on the desktop, gmc segfaults.  The associated file is
removed, so something happens before it dies.

Gtk-WARNING **: invalid cast from (NULL) pointer to `GtkBin'
Segmentation fault (core dumped)

  I think that this may be related to the bug I reported a few minutes ago
("right-clicking on icon causes gmc to crash") -- the obvious problems in the
  backtrace start with dii becoming 0x0.
