abort: command: FETCH => socket error: EOF

Backup-gmail does not complete.

I have recently upgraded to the latest kubuntu - see uname output below. I first tried running backup gmail afresh and got the following output:
rinka@personal-rinka:~/bin/backup-gmail$ Traceback (most recent call last):

-------------------
At this point I killed backup-gmail and restarted it for doing incremental backup. But there the tool is currently hanging - there are no further messages
-------------------

[1]+ Done ./gui.py

Additional information on the bug:
If I close the gui error message and restart download without closing gui.py, nothing happens. The abort cancels all activities for the current running verson of gui.py.

If I close gui.py and restart as incremental backup, backup-gmail picks up from where it stopped and continues backing up. Though it fails again with the same error a bit later.

My take: This is a transient error and should just be displayed but the tool should continue.

Happens also when running from command line.

Running on Arch Linux
with the package
