Hello!

I'm converting mailboxes from maildirs to mdbox and dsync crashes on two of them

/var/mail-nfs-1 - nfs mount /var/mail-nfs-indexes - local fs

/usr/bin/dsync -f -u user@site.ru mirror mdbox:/var/mail-nfs-1/mail/site.ru/user/mail:INDEX=/var/mail-nfs-indexes/site.ru/user dsync(user@site.ru): Panic: file istream-limit.c: line 79 (i_stream_limit_seek): assertion failed: (v_offset <= lstream->v_size)
