Title:
gnome-control-center doesn't start
Status in gnome-control-center package in Ubuntu:
Incomplete
Bug description:
gnome-control-center doesn't start. There is no crash, core dump, etc.
This bit in syslog (/var/log/syslog) gives us some information:
gnome-control-c[2962]: invalid unclassed pointer in cast to 'GtkWindow'
gnome-control-c[2962]: gtk_window_present_with_time: assertion 'GTK_IS_WINDOW
(window)' failed
Actually something similar has been seen already in the past but it
hasn't been resolved:
