gksu nautilius  

Running the above or trying to run the nautlius script -'browse as root' gives the following error

/home/borax12/.gtkrc-2.0:6: error: scanner: unterminated string constant

(gksu:3914): Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap",

Segmentation fault (core dumped)

sudo seems to work fine ,but why is the gksu password prompt not working ,the moment i type a letter in the passowrd prompt box ,it exits and give the above error.

It seems to me that you have got some customisations in .gtkrc-2.0 that are making the graphical display box for gksu abort. The error message refers to these theme engines, so you could temporarily disable that .gtkrc file, as this one in the home folder is not installed by default anyway, but contains user's tweaks for various things.

Open a terminal (by default it opens in your home folder) and run the following to rename the file, but not delete it:

mv .gtkrc-2.0 .gtkrc-2.0.backup

You could also remove .gksu.lock so you have a clean start and then test gksudo or gksu by running

gksu nautilus

If that now works, you need to examine your .gtkrc file to see what the problem was and identify if you need to use it, or what customisations you can safely keep.

If you want to reinstate the .gtkrc file, simply run (from your home folder)

mv .gtkrc-2.0.backup .gtkrc-2.0
