Right. Can we close this thread and start a new one?
(or at least rename the thread)

Yes, unfortunately.

Many applications have started refusing to launch new instances when you
execute them.
This started with browsers, but it is now affecting other types of
applications. (KDE and many recent gnome applications suffer from this)
Instead of starting a new instance, they try to show a new window -
still belonging to the first process that was started.

Now, although this can cause the application to misbehave, it should not
be able to crash the xpra server. Unfortunately, clipboard misbehaviour
is an issue that is known to cause this sort of problems.
I'll try to reproduce, having a ticket with details wouldn't hurt.

Not sure I understand this part.
