   Fix #14994; that bug was introduced in #14228 (that was my fault).

   Also this commit explicit separates There are two functions of the tray icon:

   • a system tray widget (QSystemTrayIcon::isSystemTrayAvailable() == true)
   • a high-level notificator via balloon messages (QSystemTrayIcon::supportsMessages() == true)

   These properties are mutually independent, e.g., on Fedora 29 + GNOME:

   0QSystemTrayIcon::isSystemTrayAvailable() == false;
   1QSystemTrayIcon::supportsMessages() == true;
   

   UPDATE:

   supportsMessages() makes no sense without isSystemTrayAvailable(): QSystemTrayIcon::showMessage() just not working on Fedora 29 + GNOME.

   @laanwj Thank you for your review.

   Concept ACK, TIL that those are separate

   TIL too: supportsMessages() makes no sense without isSystemTrayAvailable(). Sorry for confusing.

   PR description and commit have been updated.

    Tested c8d9d90 on Fedora 29.1-2. No longer causes a segfault when a notification appears. Created notifications using:

    0getnewaddress
    1generatetoaddress 1 the_new_address
    

    

    However, from a quick check, this seems to break notifications on macOS (10.14.2). i.e if I make deploy this PR, and run with -regtest, I no longer see incoming transaction notifications in the Notification Centre when using generatetoaddress. Be good if someone else could confirm.

    @fanquake I can’t reproduce your case. All notifications go to notification centre but they don’t popup when calling from the console window.
