This is a completely up-to-date ~amd64 system with gnome 3. When running metacity as fallback, no matter whether the system is gnome-shell capable or not, metacity crashes with the above error as soon as an application without own icons is started - simple apps such as xdvi or xev, glxgears and libreoffice are affected. I think this is the same bug that can be seen when starting metacity-theme-viewer on any system (gnome-shell or not): Loaded theme "Atlanta" in 0 seconds ** metacity:ERROR:ui/preview-widget.c:450:meta_preview_get_icon: assertion failed: (default_icon) Aborted (core dumped) This can be reproduced on all of my systems here and isn't fixed by installing metacity-themes or by changing gtk-fallback-icon-theme in /etc/gtk-2.0/gtkrc. Does someone have an idea? Reproducible: Always
Please retry with 2.34.8 on a new created user account with a new home
I believe this problem had been fixed in >=metacity-2.34.2, see upstream commit http://git.gnome.org/browse/metacity/commit/?id=234a5e217438ebfeb17555b5ab1d210e4c9820fe Please reopen this bug report if you still experience the issue after updating to the newest ~amd64 metacity in portage (currently 2.34.8).
