There you go:

janek atak:~$ xwininfo -all -id 0xc01020

... but I got a bit lost here. I have already recovered my lost
window, so I guess that status mapped/unmapped of 0xc01020 is fixed
altogether. 

I wish I had a result of this command `xwininfo -all -id 0xc01020`
_before_ window was found.

So you mean - trying to access 0xc01020, instead of 0x3000024 ?

(setq foo (get-window-by-id 0xc01020))

It's worth remembering for future - next time I'll be able to debug
this better.
