Package: speech-dispatcher
Version: 0.9.0-5
Severity: minor
File: /usr/lib/speech-dispatcher-modules/sd_generic
Usertags: crash
When I turn the Screen Reader on in GNOME via the settings or the
hotkey, I get a crash (SIGSEGV) from the sd_generic module. The screen
reader functionality still seems to work at least for GTK3 apps so I've
filed this issue as minor for now.
$ gdb -batch -n -ex 'set pagination off' -ex bt -ex 'bt full' -ex 'thread apply
all bt full' --core
