Remmina crashes using the Mir GTK backend

Remmina crashes using the Mir GTK backend.

Initially I would have blamed the gtk/gdk libraries, but it appears Remmina itself is making an X11-only call directly that's the problem:

Here's a patch that stops the crashing on non-X11 platforms.

Looks like they're waiting for a comment from you upstream. Could you try to help them out & get the patch reviewed?

Something landed in January last year. I can't confirm the status for Ubuntu because it's refusing to start right now (hence won't crash either).
