Comment 5 for bug 1917941

Okay, after doing some more debugging and digging, I found out that this may be happening due to some Gdk features getting deprecated and changed. Apparently, the asynchronous calls did not trigger the callback functions, and thus the code failed to return any data.

It would seem that this bug has already been fixed upstream.

Package maintainer, can you please bump the version of system-config-printer to 1.5.15?
