Hi,

I maintain pinpoint in Debian and I wrote some simple smoke tests to have them
run in the Debian CI infrastructure. Up until pinpoint 0.1.6, I could easily
export to PDF without DISPLAY being set (which is the case in the CI runs), but
with 0.1.8 I can't do that anymore.

0.1.6:

----------------8<----------------8<----------------8<-----------------
$ dpkg-query --show pinpoint
pinpoint	1:0.1.6-1
$ DISPLAY= pinpoint -o /tmp/test.pdf debian.pin
Unable to init server: Could not connect: Connection refused

(pinpoint:9389): Clutter-CRITICAL **: Unable to initialize Clutter: Could not initialize Gdk
$ file -i /tmp/test.pdf 
/tmp/test.pdf: application/pdf; charset=binary
$ rm -f /tmp/test.pdf
removed ‘/tmp/test.pdf’
----------------8<----------------8<----------------8<-----------------

Even though it printed a warning about not being able to connect to the X
server (fair enough), pinpoint still produced the PDF file just fine.

Now, with the 0.1.8 package I have just built, it aborts before producing the
PDF:

----------------8<----------------8<----------------8<-----------------
$ sudo dpkg -i /home/terceiro/src/debian/build-area/pinpoint_0.1.8-1_amd64.deb
