Hello.

I have tried to restore a test user mailbox and I get a segmentation fault

doveadm -D import -u ox101@us.es mdbox:/backup/bacula-restores/buzones/mysite/15/b1/ox101/ "" all

Segmentation fault/

I can fully reproduce this segmentation fault. Doveconf -n attached at the bottom of this mail. The strange this is that all mail for this user is restored, but the process segfaults.

If I strace the process the last lines are:
