#140 glabels-3-batch in headless server

[Achachiez]

Am running glabels-3-batch labelwithname.glabels --input=file.csv on a ubuntu headless server it this

Failed to connect to Mir: Failed to connect to server socket: No such file or directory
Unable to init server: Could not connect: Connection refused
LABEL FILE = labelwithname.glabels

(glabels-3-batch:22799): dconf-WARNING **: failed to commit changes to dconf: Cannot autolaunch D-Bus without X11 $DISPLAY

It generates the output.pdf just fine but I don't why it is looking for X11 or Mir
