Hi,
First, Great Congratulations for new Suricata 1.0.3/1.1beta2 release!

Second, I have a small pb with joigned pcap file.

ok first sig working:
  alert tcp any any -> any 21 (msg:"FTP format string in ftp cmd attempt"; flow:to_server,established;
  content:"%"; depth:4; offset:0; classtype:misc-activity; sid:945011; rev:1;)

ok second sig NOT working (but work with snort):
  alert tcp any any -> any 21 (msg:"FTP format string in ftp cmd attempt"; flow:to_server,established;
  content:"%"; depth:4; offset:0; content:"%"; within:2; distance:1; classtype:misc-activity; sid:945012; rev:1;)

stream:
  checksum_validation: no # or yes have same pb for me

Thx you again for your time for checking my test.
If you confirm, Im open a new ticket on suricata redmine.

Regards
Rmkml
