Invalid MIT-MAGIC-COOKIE-1

Ao tentar utilizar o firefox, via GEB, é disparada a exceção:

Caused by NotConnectedException: Unable to connect to host localhost on port 7055 after 45000 ms. Firefox console output:
Invalid MIT-MAGIC-COOKIE-1 keyInvalid MIT-MAGIC-COOKIE-1 keyError: cannot open display: :1
Invalid MIT-MAGIC-COOKIE-1 keyInvalid MIT-MAGIC-COOKIE-1 keyError: cannot open display: :1

Uma possível solução:

rm -rfv ~/.Xauthority*
