o Thanks for clarifying this.  I got the misinformation from an old
  mailing list message.

o That was the secret.  Doing `xdpyinfo -ext all` (lowercase "all")
  gives:

    MIT-SHM version 1.1 opcode: 142, base event: 77, base error: 154
      shared pixmaps: yes, format: 2

o Looking in /usr/include/X11/extensions/XShm.h shows:

    #define X_ShmPutImage                   3


o This matches what I found during a long regression testing session
  (good thing there's RCS) after posting my message.  I get the crash
  when I use a Gdk Image of type GDK_IMAGE_SHARED instead of
  GDK_IMAGE_NORMAL.  I'm going to post details in a separate message.

o Thanks again for the info.  If I had known, it would have led me
  directly to the bug.
