[Python-apps-team] Bug#714891: Still problems with 1.20.1-2

[Jeremy Sanders]

I though 1.20.1-2 (in unstable) should fix this bug, but on upgrading 
from wheezy to sid, I get:

root at lap75107:/# apt-get upgrade

You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
  veusz-helpers : Breaks: veusz (< 1.20.1-2) but 1.15-1 is installed
E: Unmet dependencies. Try using -f.

Any idea how to get this to cleanly upgrade?
