It doesn't depend on the script. Even the simplest script "stop;" gives
this error. I added two debug strings to cmusieve_deliver_mail in
cmusieve-plugin.c:

if (getenv("DEBUG") != NULL) {
  i_info("cmusieve: Using mailbox: %s", mailbox);
  i_info("cmusieve: Using username: %s", username);
  i_info("cmusieve: Using sieve path: %s", script_path);
}

and here are some more details:

deliver(mok at k...): Info: cmusieve: Using mailbox: test
deliver(mok at k...): Info: cmusieve: Using username: mok at k..
deliver(mok at k..): Info: cmusieve: Using sieve path:
/home/vmail/.dovecot.sieve
deliver(mok at k..): Info: cmusieve: Executing script
/home/vmail/.dovecot.sievec
deliver(mok at k..): Info: sieve runtime error: Keep: Generic Error

That is, if I send a message to mok+test at k.., in cmusieve_deliver_mail()
the name of the mailbox is test. For normal address mok at k.. it is INBOX:

deliver(mok at k..): Info: cmusieve: Using mailbox: INBOX
deliver(mok at k..): Info: cmusieve: Using username: mok at k..

Tested with dovecot 1.0.3 and dovecot-sieve 1.0.2.
