Bug#854295: brltty-espeak: crashes while emitting speech
Package: brltty-espeak
Version: 5.4-6
Severity: important
Hi
Every now and then, BRLTTY crashes. It looks as if there is an issue while
emitting speech using espeak-ng. I'm not sure whether the issue is actually in
BRLTTY or espeak-ng, but I couldn't encounter any issues while using
speech-dispatcher with espeak-ng yet.
The full back trace is attached to this report.
Thanks
Sebastian
