I am unable to launch Gnome System Log Viewer after setting some filters. This is so, even after rebooting and reinstalling this GUI program. I found the following relevant line in /var/log/messages:kernel - [ 2345.123456] traps: logview[1234] trap int3 ip:32682504e9  sp:7fff9123c150 error:0It seems to be some exception error with the kernel. How to deal with it and get the viewer to launch again?UPDATE:I tried launching it manually with the following command: gnome-system-log and it gives me a more verbose error:GLib-GIO-ERROR **: g_menu_item_set_detailed_action: Detailed action  name 'win.filter_hide info' has invalid format Trace/breakpoint trapIt appears that the regex I wrote for win.filter_hide has some invalid format. How can I access this and change it manually without the GUI?UPDATE2:I tried:$ gsettings get org.gnome.gnome-system-log filters@as []$ gsettings reset org.gnome.gnome-system-log filtersIt doesn't work. I think I am somewhere close, but not sure how to access win.filter_hide from here. From this image, I don't see how installing dconf-editor would help me access that filter.UPDATE3:I finally manage to take a peep at the values by logging in as root:# gsettings get org.gnome.gnome-system-log filters['hide info:1:::\\tinfo', 'error:0:#efef29292929::\\terr', 'show all:0:#000000000000::\\d']# gsettings reset org.gnome.gnome-system-log filters(process:3453): dconf-WARNING **: failed to commit changes to dconf: The connection is closedNot sure where is the problem. But as can be seen, I can't even do a reset when logged on as root. And I can't access those values when logged on as normal user.UPDATE4:Finally it is solved. The reason why connection is closed is because the root is logged in the user environment. This should work:$ su -c gsettings reset org.gnome.gnome-system-log filters -
Unable to launch Gnome System Log Viewer after setting filters

The filter settings are saved as a gsettings scheme: org.gnome.gnome-system-log.filters. You can edit them with dconf-editor (org>gnome>gnome-system-log>filters). Replace the space in the name of the filter with a dash (or some other character), and gnome-system-log will work again.
