Fail to print preview

[dionysos-sf]

When I tried to do a print preview of a sheet, I get the following error message in the console:

(oregano.bin:4210): Gtk-WARNING **: Error launching preview Failed to execute child process "evince" (No such file or directory)

Nevertheless, okular is open with an empty sheet but with the title block.

Does it show the black wire to wire connection blobs or is it an enterly white sheet (except for a few rectangular shapes)

I didn't notice before, but I can see the black connection points of the schematic. And the title block, of course.
