[Dovecot] Panic: file mail-index-transaction-export.c: line 203 (log_append_ext_hdr_update): assertion failed: (u32.offset + u32.size <= ext_hdr_size)

Unfortunately, I'm still getting the same errors post upgrade to 2.2.13.

I'm coming from 2.1.12, so perhaps there is some slight incompatibility 
in some circumstances with the index files? I'm continuing to delete 
them as this arises, and so far I've no repeat problem accounts.
