v0.16.0rc4 on Fedora 27
After probably several hours v0.16.0.rc4 crashes. I have observed this only (that I can confirm) in the past two days.
The first time it was loaded on login and I came back to my PC and it was gone from the tray so, I restarted it from the command line.
The second time I do not recall if I left the window open or if it was running in the tray (topicons-plus) however, I this time have an error message in the console:
>bitcoin-qt
Gdk-Message: Error 22 (Invalid argument) dispatching to Wayland display.
>
Nothing useful in debug.log
Obviously, I will now try v0.16.0 release.
