Playing with the new idxview I got this error running against my INBOX dovecot.index.cache file. What exactly does it mean?

Full output:

# /usr/libexec/dovecot/idxview dovecot.index.cache -- INDEX: dovecot.index.cache version = 1.8 base header size = 0 header size = 1170103198 record size = 1170103283 compat flags = 7 index id = 0 flags = 26512 uid validity = 0 next uid = 2460778624 messages count = 0 recent messages count = 632 seen messages count = 1 deleted messages count = 1140057508 first recent uid lowwater = 4294966816 first unseen uid lowwater = 3 first deleted uid lowwater = 1836 log file seq = 0 log file int offset = 2 log file ext offset = 1140057513 sync size = 266287972361 sync stamp = 21 day stamp = 0 day first uid[0] = 1378709065 day first uid[1] = 2037149797 day first uid[2] = 980374573 day first uid[3] = 826620960 day first uid[4] = 2019113286 day first uid[5] = 808463731 day first uid[6] = 1279801136 day first uid[7] = 1078085165 Fatal: file hdr read() 41984 != 1170103198

('idxview dovecot.index' and 'logview dovecot.index.log' come back without any Fatal type errors, just gobs of information)
