[orca-list] Orca and caja file manager?

[tim <isfeldt gmail com>]

    Hello all, so apparently either this is a bug, or something, but 
serious enough to investigate, and if possible, I'll provide a debug 
log, but even with the latest caja installed, orca 3.20.2, when copying 
a large directory several gigs to several hundred gigs, if one doesn't 
constantly alt tab between windows often, and say leaves the transfer to 
go do something else, or another instance of this issue occuring is just 
as the transfer is finished, but it more happens during transfer, loss 
of the keybord entirely, including speech, the only resolution I've 
found is to using the good ol magic sysrq key and either rebooting or 
powering off the machine.  I'm not sure weather the copy/moving of the 
directory/files is still going on in the background or not being as once 
it happens even attempting to access a console won't work, it's as if 
the keybord is useless. This only happens with quite large directories 
though.  Again I can provide a dbug log if need be. This is sonar 
2016.3, and this isn't the first time this has happened, it happened a 
few caja versions back, though I'm not sure if it's caja specifically, 
or what the heck it is.  Any ideas on this weird anomaly?
