It's your template, just with t_nodot replaced.
Even used an empty string there.
Tried this
Code:
program:
t_dot = '';
t_nodot = ''
and it stops with a syntax error on "program:"
Could it be that I have to install calibre from scratch, deleting every single trace it left anywhere on my machine? I try that first before we have to think too much.
-> Ok, done that ... same problem as before
