I thought about the same thing while following the wiki guide. But in 
the end it's just the name of a bash script. Now I changed it as you 
proposed, since it just makes more sense, but the error remains:

Error: program `/usr/lib/dovecot/sieve/rspamd-learn-ham.sh' terminated 
abnormally, signal 11
Error: sieve: pipe action: failed to pipe message to program 
`rspamd-learn-ham.sh': refer to server log for more information.
