Actually, you seem to only have changed a file name in an splot command 
a couple of lines before the 'fit'.

And FWIW the bug doesn't reproduce on version 4.2.3 in Windows.

Which, to me, suggests this might be something particular to the Debian 
release package.  Could you build your own gnuplot from our official 
source tarball and see if this still triggers?

Oh, and you may want to lose the bigger-than-one size settings.  Please 
see "help set size".
