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

Hey Peter.

I just tried this in Fedora 25 using Transmission 2.92 which claims to
be using QT version 5.7.0. No crash here using the steps you provided below.

That said, if a Qt app is crashing as a result of Orca examining
accessible objects in that app, the bug is likely in the app or the
app's toolkit. Are you able to run transmission-qt under gdb? If not, if
you launch transmission-qt from within a terminal, does it provide any
output when the crash occurs?
