Yes, doing that way reproduces the crash.

But you must also do the following steps to get the crash.
Sorry that I forgot to mention them:

3. C-z
4. C-z

Step 3 thumbifies the frame. Step 4 should dethumbify it. C-z is a toggle to
replace iconify/map by thumbify/dethumbify.  Step 4 crashes Emacs.

Compare with a build of 7/19 or prior, to see the expected behavior.

Thx.
