It's quite easy to catch unix signals in Qt applications. you may like to ignore or accept them.

#include <QCoreApplication>

#include <signal.h>
#include <unistd.h>

Seeing this error in the bash shell when launching some apps, such as scite:

** (scite:5298): WARNING **: Error retrieving accessibility bus address: org.freedesktop.DBus.Error.ServiceUnknown: The name org.a11y.Bus was not provided by any .service files
