I had this problem as well. After quick googling I found out that they had
similar issue in software called Gajim.
Here is explained why is this happening:

They solved it like this:

I adapted their to solution to backintime, diff is included as an
attachment. I've been using this fix for a few days now and I haven't
noticed this problem anymore.

Bug description:
I use cron to run "backintime -b" (I also tried "backintime --backup-job" but
the problem is the same) as a normal user who has write access to the snapshots
path. In most cases the backup doesn't work. The systray icon says "Compare
with snapshot ..." and the output of backintime is

There remain 2 processes running forever:

When I run backintime -b manually, it does work (at least I had no case where
the same error occured until now).
I have Python 2.6.3 installed.
