[orca-list] periodically losing access to qt application menus

[kendell clark <coffeekingms gmail com>]

hi all
I seem to be having a weird problem that I'm not sure what the cause is. A week or so ago, I noticed that I 
couldn't get 
orca to read the menu contents of any of my qt applications. vlc, virtualbox, etc. I can get the menu titles 
to  
announce by pressing either alt or f10 to open the menu bar, and I get file, media, edit, etc. But the minute 
I press 
down arrow to go into the menus orca stops reading the menu items. Pressing escape to close the menus brings 
the menu 
bar back, which makes the menu bar speak. I've found  what seems to be a fix, but only a temporary one. 
Removing 
my orca 
settings from ~/.local/share/orca restored them, but tonight they've gone again. I have qt-at-spi installed, 
and qt5 
apps don't seem to be affected as much. Can anyone else reproduce this, or have any idea how or why this 
happens? On 
another strange note,  qt applets in mate pannel don't announce with orca, but this could be applet specific, 
and not a 
problem with qt in general
Thanks
