almost empty files put in Sent when syncing

[Hans Ekbrand <hans.ekbrand@xxxxxxxxx>]

Hello list!
When syncing Maildir/Sent, offlineimap leaves a file at the server, a
new additional file every time. The file only contains one line: E.g.

X-OfflineIMAP-x817185232-52656d6f74654578616d706c65-53656e74: 
1176196230-0224649044387-v4.0.11

I removed all such files from the server and then synced. Here is what happened:

Here is the content on the server before syncing:

[11:03:44]hans@debian:~>ls -lSs Maildir/.Sent/cur/ | tail

And after the sync.

Why does offline imap put files there?
