当QT编译代码或者运行可执行程序出现：Couldn’t register with accessibility bus: Did not receive a reply信息：

(MG-APPS:11962): dbind-WARNING **: 09:28:02.772: Couldn't register with accessibility bus: Did not 
receive a reply. Possible causes include: the remote application did not send a reply,
the message bus security policy blocked the reply, the reply timeout expired, 
or the network connection was broken.

According to https://wiki.archlinux.de/title/GNOME#Tipps_und_Tricks, this warning can be put off by setting

export NO_AT_BRIDGE=1

in /etc/environment.
