[offlineimap] Can't save a zero byte message (#216)

[Emmanuel Geoffray]

Hey there,
I have an issue with offlineimap crashing with the server replying "Can't save a zero byte message"
Any idea why would offlineimap try to sync a zero byte message?
My hard drive was ful lately, do you think the issue started from there?

Here is the log 
```
