[Dovecot] pop3c migration?

OK so now I tried a doveadm backup -R with pop3c using dovecot 2.2.4
(50117c22151e) (auto build) and it works fine, and indeed very fast.
Funny, I ran into a segmentation fault by mistakenly passing
pop3c_password instead of imapc_password, thought it would be worth posting.
I'm using the cutting-edge dovecot over NFS storing to the production
server running 2.1.7. I'll be seeing "Corrupted index cache file ..
Invalid magic in hole header" when every account logs in for the first
time post-migration. Is this OK? I'm using Maildir.
Segfault:
Starting program: /usr/bin/doveadm -D -o imapc_user=xxxx at example.com -o
pop3c_password=******* -o imapc_host=mail01.example.com import -s -u
xxxx at example.com imapc: '' NOT mailbox INBOX
