Yes, thanks for providing this backtrace. Meanwhile, I
seem to be hitting the same (or some related) issue
on some machines here myself. I am pretty concerned about
this, since it seems extremely hard to track, at least
for someone with barely any CORBA knowledge. From what
I can see, the real problem is hidden in the backtrace
because the CORBA calling-chain is involved.
I also observe gnome-speech using applications that seem to
launch a festival-synthesis-driver process that ends up
consuming 100% CPU and hanging the application that
is trying to use gnome-speech to deliver output.
Maybe those two issues are related, however, I do not
know how to even begin debugging the second one, since
gdb on the app that is using gnome-speech does not
show anything since the problems seems to be
in a different process?
Does anyone with more CORBA know-how know how to debug this?
At least the first (test-speech crashing) is
easy to reproduce:
install libgnome-speech3-dev
then:
