On December 31st, 2016, I restricted third party access to the Geany Github organization because the previous settings were pretty much open (I noticed while coupling readthedocs.org with my personal Github account and got flooded with Geany repositories which was quite surprising).
I just re-granted organization access to the geanyadmin user which is used for the Travis integration. I'll try to trigger a build for this PR and ideally we will see the results then again.
