A typo when transposing to email.

This is still basically what I was doing before, just negating the multiple
calls to lookup_widget().  It's still segfaulting, here's the backtrace from
gdb:

#0  0x41f0c8 in gdk_bitmap_ref () from /usr/lib/libgdk-1.2.so.0
#1  0x3fa1f8 in GTK_TYPE_GDK_COLOR () from /usr/lib/libgtk-1.2.so.0
Cannot access memory at address 0xafc3815b

Is gdk_pixmap_create_from_xpm allocating memory for the mask, because I'm not..
 The segfault itself is occuring within the gtk_pixmap_set call.

Chris
