Remmina quits silently after closing RDP or main Remmina window

I have had a problem with Remmina for the past three weeks.

I have started Remmina by using: remmina -i
It is then placed in the system tray correctly.

I'm working normally, start RDP and close the connection, the whole Remmina app closed with it.

If I start for example the main Remmina window and close the window, Remmina is closed with it.

But if I will keep the main Remmina window opened, start RDP and close RDP connection, Remmina is still active correctly, because the main Remmina window is still open.

It seems there is some problem with the window handles, and wrong mapping that no window is present, the Remmina main thread is killed, or something like this.

It happens on all my workstations, 10 computers.

No error present in output.
