Error when running gtk-redshift

You may need create a config file to avoid the crash..

Create a file named redshift.conf and save it into ~/.config/redshift.conf. Here you have an example to create the config file:

; Global settings
[redshift]
temp-day=5700
temp-night=3500
transition=1
gamma=0.8:0.7:0.8
location-provider=manual
adjustment-method=vidmode

; The location provider and adjustment method settings
; are in their own sections.
[manual]
lat=-34.6
lon=-58.3

;screen
[vidmode]
screen=0

To know the coordinates for your city you can use itouchmap. Just search for your place and write down the numbers.
eg: My city Buenos Aires is lat=-34.6 and lon=-58.3

Once you have created the redshift.conf file, run the application and see if it works. You can find additional information about commands, config file, values on the Redshift website...
