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

Hi there, just to report back on this, I also discovered that mumble-git 
package (devel version of mumble that switched away from qt4) is also 
unstable. I can't connect to a server with orca running, because that 
makes the program exits with a segmentation fault. I suspect that is 
something really related to most qt5 apps, like qt5-tools, or qt5 itself 
because all those crashes are pretty much the same. As for pcmanfm, I 
tried running it in gdb, but couldn't find a thing since the packages 
were stripped (they usually do in arch). I'll try investigating more.
