Unfortunately i have to continue this issue.
During my last updates this problem is occured again. This are my versions:
# 2.2.21 (): /etc/dovecot/dovecot.conf
# Pigeonhole version 0.4.11 (6ddf62b87f60+)
# OS: Linux 3.13.0-77-generic x86_64 Ubuntu 14.04.4 LTS

I tried to configure the linebreaks in my plugin section of 
/etc/dovecot/dovecot.conf by:
sieve_extprograms_input_eol = lf

But it seems to have no effect. Is this configured the right way or i 
have to use 0.4.12?
Currently it looks like this:

plugin {
   sieve = ~/sieve/.dovecot.sieve
   sieve_before = ~/sieve_before/.dovecot_before.sieve
   sieve_after = ~/sieve_after/.dovecot_after.sieve
   sieve_plugins = sieve_extprograms
   sieve_extensions = +vnd.dovecot.pipe +vnd.dovecot.filter 
+vnd.dovecot.execute +editheader
   sieve_pipe_bin_dir = /usr/local/bin/
   sieve_filter_bin_dir = /usr/local/bin/
   sieve_dir = ~/sieve
   sieve_global_dir = /etc/dovecot/sieve/
   sieve_extprograms_input_eol = lf

}
