[orca-list] Orca getting stuck while reading messages in Thunderbird

[Vojtěch Polášek <krecoun gmail com>]

Greetings,
I don't know how to reliably reproduce this, but it happend to me. I am
running Arch Linux with Thunderbird 38.2.0 and Orca from master.
Sometimes while reading a message Orca simply stops reading anything in
Thunderbird. Sometimes if I do several alt+tabs it solves it self,
sometimes I have to restart Orca to fix this.
Could anyone try this?
Thanks,
Vojta
