[Dovecot] How to create managesieve core dumps

[Pascal Volk]

I've found this in my dovecot.log:

`--                                                                             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Dovecot v1.2.1/f353c5b71097 was started with:
    host ~ # ulimit -c unlimited
    hots ~ # /usr/local/dovecot12/sbin/dovecot
    ILoading modules from directory: ...
    IEffective uid=65534, gid=65534, home=/tmp
    ...                              ^^^^^^^^^
    IEffective uid=65534, gid=65534, home=/tmp
                                     ^^^^^^^^^

Why is Dovecot not dumping a core and asking: »is home dir set?«?
