I forwarded the issue to upstream's bug tracker with some detailed way to reproduce it. You can follow further progress there - just register at its.freebsoft.org and subscribe notifications for the specific issue (https://its.freebsoft.org/its/issues/7500), or alternatively for the whole Speech Dispatcher project if you are interested in other Speech Dispatcher bug reports as well (https://its.freebsoft.org/its/projects/1876). Or you can just view the issue at that address without registering, but you won't get notifications on new comments and won't be able to add your comments.
Anyway, when there is a conclusion available in upstream's bugtracker, I will update this bug with it and act accordingly. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
