I detach the GNU Screen session, thus the "screen" command ends,
so that the shell script started by xterm also ends, and xterm
quits as a consequence. I detach the GNU Screen session by doing
"^z d" (where ^z is the command character in my Screen config).
So, fvwm is not involved at all concerning the window destruction.
Note: I could reproduce the bug by running my script in xterm, then
hitting [Enter] to place the window, then ^z d (so, the mouse is not
used at all).
I can't reproduce the bug when fvwm is running under valgrind.
However, I note various valgrind errors (see attached file).

This is quite difficult as it takes time to reproduce the problem,
at least for the first time (then it seems to occur more often until
I restart fvwm, but I'm not sure). And it doesn't mean that you
would be able to reproduce it as it seems to be timing dependent.
It may be better if fvwm had internal logging mechanism and/or
assertions to see what's going on.

Sorry, one problem is the lack of quotes in ps output, and forgot to
add some of them. This should be:
/usr/bin/xterm -xrm "*printFileOnXError:
/home/vlefevre/private/xterm-saved-1487164622-23460" +sb -sl 0 -n "Mutt -
cventin" -T Mutt -e sh -c "smutt || { echo 'Press [Enter] to quit.'; read x; }"
You don't have the smutt script, but this should be equivalent to
something like: ... -e sh -c "exec screen -dRR"
The -dRR option is:
-d -RR Reattach a session and if necessary detach or create it. Use
the first session if more than one session is available.
