DBus Spawn ChildExited Error
Hi, I am currently doing some work with the Gnome-Control-Center printing panel ans CupsPkHelper .The G-C-C does a gdbus_connection_call to cups-pk-helper for discovery of printer devices. This discovery method is currently being replaced with PAPPL & some other API calls.
The problem is that as soon as I add PAPPL API calls for this, the G-C-C throws an error (gnome-control-center:11427): printers-cc-panel-WARNING **: 13:39:39.747: GDBus.Error:org.freedesktop.DBus.Error.Spawn.ChildExited: Launch helper exited with unknown return code 127
.
I have tried looking up for a solution but couldn't find anything useful.
