Package: at-spi2-core
Version: 2.22.0-6+deb9u1
Severity: normal
Dear Maintainer,
I am seeing warnings when starting Emacs:
** (emacs:5181): WARNING **: 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.
This happens every time.
I have found other reports on the internet from a few years ago but they seem
to have been marked fixed or abandoned.
One commonly suggested solution was to put
export NO_AT_BRIDGE=1
in ~/.profile. I have successfully done this in the past but this no longer
works for me.
reportbug itself also gives the same message when started in graphical mode so
this is not emacs specific.
I ran the check-a11y/troubleshoot tool provided by Samuel Thibault. The output
is:
$ ./troubleshoot
