--- Comment #13 from David C. Bryant <davidbryant at gvtc.com> ---
I think this problem has been fixed. I'm using Gentoo Packages, KMail 5.16.3,
Plasma 5.21.5, Frameworks %.82.0, Qt 5.15.2.

The menu item "File --> New --> Main Widow" has been removed. Simply starting
KMail, then saying "kmail" in a terminal window won't fire up a second instance
of the program. But "d-bus-launch kmail" will start a second (and a third)
instance of the program.

I fiddled around with this for a bit, and could not get any of the instances of
KMail to crash. I could navigate to different folders / messages. I ran "qps"
(traces process ids, like a GUI version of "top"). I saw multiple instances of
the akonadi server running, which might eventually cause a problem. Memory
usage was pretty high. Killing the extra instances of kmail left "phantom"
instances of akonadi hanging around ... I'm too lazy to try killing them one by
one, so will probably just reboot to clean up the process tree..

The only really odd thing I noticed is that the system tray icon was not
recreated when I opened a second main KMail window. And if I "quit" from the
system tray, the second instance of KMail keeps on running.

Does anybody have any objection to marking this bug "resolved"?
