since you are having problems in reproducing the bug and the crash is
predictable, I suspect that these are symptoms of a hidden memory
corruption in a library.
My theory is that while using Openbox the panel does not access an
invalid pointer (probably thanks to some abstractions) but with xfwm4 it
does. This problem is the same but in the 1st case it remains hidden.
To verify my theory I replaced Openbox with xfwm4 and killed compton and
all the desktop gadgets.
Then I repeated all the actions of the video and the panel crashed and
To debug the panel I killed xfce4-panel and executed it under dgb. Even
without the debug symbols I discovered
the position of the bug: "tasklist-widget.c" @ line 2681. This should
be, at least, a good place to start.

If I can do something else, I'll be glad to help.
