[Dovecot] LDA panics without sieve script

[Jürgen Obermann]

The dovecot lda panics with "Trying to sync mailbox INBOX with open
transactions" if a user has no sieve script defined. Debugging shows:

Sep 14 19:49:26 server dovecot: [ID 583609 local0.debug] lda(userxx):  
Debug: sieve: user's script path /home/grp/userxx/.dovecot.sieve  
doesn't exist (using global script path in stead)
Sep 14 19:49:26 server dovecot: [ID 583609 local0.debug] lda(userxx):  
Debug: sieve: user has no valid personal script
Sep 14 19:49:26 server dovecot: [ID 583609 local0.debug] lda(userxx):  
Debug: sieve: no scripts to execute: reverting to default delivery.
Sep 14 19:49:26 server dovecot: [ID 583609 local0.crit] lda(userxx):  
Panic: Trying to sync mailbox INBOX with open transactions
Sep 14 19:49:26 server dovecot: [ID 583609 local0.error] lda(userxx):  
Error: Raw backtrace: 0xff1cc2ac -> 0xff1cbb70 -> 0xff2a6474 ->  
0xff2a668c -> 0xff2fa444 -> 0xff2a63c8 -> 0xff2668ec -> 0xff266f74 ->  
0xff26741c -> 0x12720 -> 0x11948

I then did create an empty sieve script file with
touch /home/grp/userxx/.dovecot.sieve
and after that lda worked:

Sep 14 19:50:55 server dovecot: [ID 583609 local0.debug] lda(userxx):  
Debug: sieve: using sieve path for user's script:  
/home/grp/userxx/.dovecot.sieve

Sep 14 19:50:56 server dovecot: [ID 583609 local0.debug] lda(userxx):  
Debug: box=/var/mail/userxx mount=/var/mail match=yes
Sep 14 19:50:56 server dovecot: [ID 583609 local0.info] lda(userxx):  
sieve: msgid=<201109141750.p8EHotbE015854 at server.hrz.uni-giessen.de>:  
stored mail into mailbox 'INBOX'

I think the lda worked in previous releases without a sieve script  
file in the users home directory.
