zlib inflate error: -3 invalid literal/lengths set / Error decompressing data, closing connection

[Tomasz Chmielewski]

My Android IMAP client (K-9 Mail) is no longer able to download new 
messages from Cyrus. Other email clients work fine.

In Cyrus logs, I can see the following entries:

     created decompress buffer of 4102 bytes
     created compress buffer of 4102 bytes
     zlib inflate error: -3 invalid literal/lengths set
     Error decompressing data, closing connection

Google is not too helpful withe these.

Does anyone know what causes this error, and how to fix?
