I experience no problems whn gtk-qt-engine is uninstalled. I get different gtk error messages:
With gtk-qt-engine installed: (gnome-appearance-properties:12009): Gtk-CRITICAL **: gtk_widget_map: assertion `GTK_WIDGET_VISIBLE (widget)' failed (gnome-appearance-properties:12009): Gtk-CRITICAL **: gtk_widget_map: assertion `GTK_WIDGET_VISIBLE (widget)' failed Without: (gnome-appearance-properties:13339): Gtk-WARNING **: Unable to locate theme engine in module_path: "murrine", (gnome-appearance-properties:13339): Gtk-WARNING **: Theme directory 32x32/emotexs of theme Aqua-Glade_PNG has no size field Since there is no real crash happening here (at least gdb doesn't interpret one when the program hangs), I seem not to be able to supply any backtrace. While the program is hung I cannot write "backtrace full" to gdb and a click on the X in the top right corner just produces "Program exited normally." without leaving any "backtracable" stack to look into. ** Changed in: gnome-control-center (Ubuntu) Status: Invalid => New -- Desktop Appearances Properties crashes repeatedly - gnome-appearance-properties crashed with SIGSEGV in XSetCloseDownMode() https://bugs.launchpad.net/bugs/189509 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
