I'm still getting this error in the 1.1.x hg tree (using a post 1.1.11
snapshot taken 6 days ago), happy to see I'm not the only one.

It's really _rare_ and difficult to reproduce.
Usually, it happens when a thunderbird user tells dovecot to store a
mail with multipart mime attachments in a mbox folder (mostly Sent or
Trash folder).

When this error appears, the last mail attachment is actually truncated.

Filesystem here is ext3 on a two node drbd active/passive cluster (Centos 5.2)

Diego.
