I start wireshark from the commandline without any arguments.  I see the wireshark window pop up for a moment, and:
$ wireshark 
QSocketNotifier: Can only be used with threads started with QThread
Segmentation fault (core dumped)

wireshark-3.2.3-1.fc32.x86_64
qt5-qtbase-5.13.2-5.fc32.x86_64
qt5-qtbase-gui-5.13.2-5.fc32.x86_64

I also tried removing ~/.config/wireshark in case there was something unusual there, but got the same result.

I believe my setup is pretty much default F32, though I've been running it a few months and already upgraded once or twice, so there might be something I've changed and forgotten.
