gnome-terminal-server crashed with SIGABRT in g_assertion_message_expr()

[bruno dias da silva]

When resizing a gnome-terminal window while mutt (email client) is open when reading email,
all open terminals are automatically closed. The same is true for other emulators, like: Terminator and Tilix.

The update-notifier-crash shows that the problem binary is in "/usr/libexec/gnome-terminal-server"

I noticed that when using mutt through some pseudo-terminal (like tmux), the bug takes longer to happen.
