Comment 8 for bug 677783

I wrote the author/maintainer a couple of months ago to see, if he's still active. No response so far.
That leaves us (and me) the possibility to fork redshift into a PPA.

For the time being you can apply either of my patches (preferably the latter) to /usr/share/pyshared/gtk_redshift/statusicon.py, if you don't want to rebuild from source.
