The sieve parser state doesn't get reset properly after an error.  Thus
once a script fails to parse, all scripts will fail to parse (try to
submit a good script after a bad one in a timsieved session to see this in
action).

If badly-formed sieve scripts could have snuck in, then this will affect
lmtpd as well, leading to behavior like you describe here.

The bytecode, of course, solves this problem (But that won't ever be seen
in 2.1)
