[orca-list] Orca segfaults

[Nolan Darilek <nolan thewordnerd info>]

I'm experiencing lots of Orca segfaults when listening to MP3s in 
Firefox. Based on this debug log, it looks like it might have something 
to do with progress bars? Not sure if this is an Orca or pyatspi issue, 
but thought I'd send the log here for further insight. Orca master, 
Firefox 56, everything else is stock Fedora 26 with all updates applied.


Thanks!
