[BRLTTY] Crash of BRLTTY in X session

Tue Nov 5 09:52:19 UTC 2024

Hi

With BRLTTY 6.7, BRLTTY crashed while I was using Orca in the X session. The
back trace is below. I'm using Debian stable with a backport of BRLTTY.
Is there anything else I could provide to get this fixed?

Thanks in advance!
Sebastian
