Sorry, I seem to have failed to respond to this before (or my response
never made it to the BTS). I certainly did take a look before as I
found your repoducer script on my disk...

I can reproduce the crash, but it appears to be connected with the
removal of tmpfile-plot - if I add:
sleep 5
before the "rm" command then I can use the scroll wheel for 5 seconds
but then get the crash after that - presumably changing the viewing
area causes gnuplot to try to reload the plot file or something like
that?

Hmm, I don't seem to get a core file (and sadly am struggling to work
out how to enable them on current Debian).
But repeating that after installing these packages (assuming unstable)
would be more enlightening:
libwxbase3.0-0v5-dbgsym libwxgtk3.0-gtk3-0v5-dbgsym
Cheers,
Olly
