i have enabled the zlib plugin with xz compression but on some new  
mails i got now a segfault and the following lines in dovecot error.log

Dec 12 08:51:23 imap(tester at domain.com): Error:  
lzma.read(/srv/vmail/mail/domain.com/root/storage/m.3): unexpected EOF

the problem is that the mails can't be shown. this happens not with  
every mail i also got new mails that can be shown without any problem.  
i was not able to produce a coredump
