Package: icedove
Version: 3.1.16-1
Severity: minor
Email stored on a Debian server using dovecot (1:1.2.15-7) was accessed using
icedove over Imap4, synchronisation is set to keep a copy of all messages
locally.
On occasions unexplained file growth was seen with these lines (date varies and
is current system date):

.... lots of encoded data follows...
Were concatenated onto the end of the file in the
{profile}/ImapMail/mail.technocool-1.net/Personal repeatedly. This led to rapid
file growth and disk space exhaustion if Icedove was left running.
Compacting the corresponding folder caused the repeated copies of the data to
be removed.
On inspection a file simply consisting off this Base64 encrypted data without
normal mail headers nor any other content was to be found in the corresponding
"cur" directory of the maildir.

A copy of this file has been retained, the origin of the corrupt file is
unclear.
I would have hoped that the situation would have been handled more gracefully,
I was able to identify the issue and take action only because I have access to
the maildir on the Imap server, otherwise the end user is left with a file that
grows out of control and no indication other than the repeated content as to
origin.
I've assumed since dovecot has only one copy of the file that it is probably
doing the right thing and that the issue lies with Icedove.
