Dear Maintainer,

Some emails causes a crash of dovecot, when i try to show them in
horde. This only happens in virtual folders created by the
virtual-plugin. Show the same emails in the original imap-folder there
is no problem.

This only happens with horde, but it is a dovecot-problem. I filed a bug
on the dovecot mailinglist, and they fixed this today.

I got the fix this morning and tried it. It works for me.

Can you include this fix also in stable (or even backports?)

Jakob
