F19: GDK_IS_WINDOW (window) failed

Good morning List,

I have recently upgraded to F19 and since have a problem when I work with Emacs: after a short while I get the error message "Gdk-CRITICAL **:gkd_window_get_height: assertion 'GDK_IS_WINDOW (window) failed". (I'm using Gnome.) Emacs freezes then...

Search on the web gave me a number of hints (like re-installing bash) but none of that worked. Has anyone else encountered a similar phenomenon? Is that a bug (possibly gtk2 related, as some comments on similar exprience with older versions of Fedora, but also other distributions, suggest)?

Thanks for any help
Peter
