bug#66978: 30.0.50; crashed when closing one of two frames

[Gregor Zattler]

This (see below) is a backtrace from a crash after I
closed one of two graphical frames associated with the
same Emacs daemon.

Tried to reproduce it, but couldn't, so don't know if
this is helpful, if so I'm happy to answer questions,
but the process is already killed.

Ciao; Gregor
