Re: [orca-list] orca makes qt5 applications extremely unstable (or maybe at-spi ?)

Hello,


Thanks for your time and for all the hints you have posted to the list 
today.


It turned out that I was running Gnome on Wayland and this is a Wayland 
migration related crash. If I run transmission-qt in Gnome on X.org, 
it's running with no crashes like I've explained earlier.


Greetings


Peter
