Kleper,

I was able to reproduce this problem on my computer.  It turns out the
problem was a typo.  You can fix this on your computer relatively easily.

Download this file from the git repository:

  https://raw.github.com/bruceravel/demeter/master/lib/Demeter/templates/report/standard/setme.tmpl

It is a one-line file.

Now find where Demeter is installed on your computer.  On Windows, it
is probably C:\strawberry\perl\site\lib.  On linux you can figure it
out by typing the following at the command line

  perl -e 'use Demeter;use File::Basename;print dirname($INC{"Demeter.pm"})'

Move the file you just downloaded to 

   Demeter/templates/report/standard/setme.tmpl

under that location.  The correct folder has a bunch of files with the
.tmpl extension.  The first in the list shoudl be "after.tmpl".

Once you put that one-line file in the correct place and with the
correct name, the crash you experienced will not happen again.

This will, of course, be corrected in the next release.  And this fix
has already been pushed to github.

Thanks for finding this problem,
B
