It's apparently a GTK bug, failing to pass a parent pointer:

MirWindowSpec* mir_create_modal_dialog_window_spec(MirConnection* connection,
                                                   int width, int height,
                                                   MirWindow* parent)
{
    mir::require(mir_window_is_valid(parent));

Although that might also be correct... Does it have a parent?

OK, from the duplicate bug I can see the common theme. We either have buggy toolkits, or just some legacy apps expect to create "modal" dialogs without a parent window. I'm not sure if that's an app bug, but Mir will certainly abort() if you ask for that.

Seems like the right answer in some cases might be:

MirWindowSpec*
mir_create_dialog_window_spec(MirConnection* connection,
int width, int height);
