Well, the question is then.. Why were the corrupted in the first place? Based on your previous error message it looked like the cache file contained the compressed size, so maybe zlib plugin wasn't loaded for some Dovecot process at that time?
Anyway, yeah, I guess there are two potential improvements here: Either a) don't rename maildir file if S=size is different from cached size or b) rename the S=size to the correct decompressed size (=no renaming if it's correct). Not sure which one is easier to do, possibly b) and possibly it should be done anyway.
In any case, I think this is a good addition: http://hg.dovecot.org/dovecot-2.2/rev/6d9444ea1c9a
