Well, I get:
    id,name,from,to,src-address,dst-address,service,action,nat_status,nat_type,nat_src_ip,nat_dst_ip,nat_dst_port,log,schedule
    1000,Test Rule Temporary ,DMZ Web,Trust,"sparkeregap1, sparkeregap2","maxprddb-scan-167, maxprddb-scan-168, maxprddb-scan-169","1521, Oraccle-Maximo-Scan-1550, PING-ALL",permit,,,,,,"Enable, session-init",
    4000,,DMZ Web,Trust,"sparkeregap1, sparkeregap2","sparkcas01, sparkcas02, email.ab.spark.net",SMTP,permit,,,,,,"Enable, session-init",Mar 2012

So there is something different on your system.


By the way: next time make sure that we can copy paste your code:
- dic_2 does not have a '='
- get rid of the space before my_list
- make sure the '[' is at the same line as my_list (or use a \)
