Dear maintainer,
when I attempt to open the printing dialog from atril or Firefox, the
application freezes as soon as CUPS is accessed. CUPS itself works fine,
as I can print from the command line with "lp", show the available
printers with "lpstat -p", and print a test page via the web interface
at localhost:631.
Debugging atril yielded the following transcript (I just opened a random
PDF file and pressed Ctrl+P):
