[Dovecot] core dump in mail_cache_header_fields_read()

[Wesley Huang]

Hi Timo,

The patch works. With the error log we identified a corrupted cache file 
for the Trash folder (not the cache file for the inbox we previously 
suspected).  After having this cache removed, we don't see the error any 
more.

Thanks again!


Cheers,

Wesley
